(Round to one decimal place as needed) c) Do the two percentages agree? Why or why not? OA. Yes, because a Normal probability plot shows that the Normal model is appropriate OB. No, because a Normal probability plot shows that the Normal model is appropriate O C Yes, because a Normal probability plot shows that the Normal model is not appropriate O D. No, because a Normal probability plot shows that the Normal model is not appropriate
The two percentages do not agree. Hence, option D is correct.
a) The mean time was 103.59 seconds, with a standard deviation of 5.16 seconds. If the Normal model is appropriate, the percentage of times that will be less than 98.43 seconds can be calculated as follows:
z = (x - μ) / σz = (98.43 - 103.59) / 5.16z = -1.00Using z-score table, we can determine that the percentage of times that will be less than 98.43 seconds is approximately 15%.
Therefore, the percentage of times that will be less than 98.43 seconds is 15%.
(Round to the nearest integer as needed)Hence, option A is correct.b) The actual percentage of times less than 98.43 seconds can be calculated by finding the number of competitors that finished with a time less than 98.43 seconds and dividing that number by the total number of competitors.
98.06, 98.09, 98.46, 98.47, 98.96, 98, 99, 99.12, 99.35, 99.57, 99.98, 100.08, 100.11, 100.28, 100.64, 101.32, 101.06, 101.25, 101.34, 101.39, 102.48,
101.99, 103.01, 103.87, 104.11, 103.64, 104.15, 104.27, 104.37, 104.33, 104.52, 105.47, 105.48, 105.69, 105.61, 113.02, 105.73, 109.65, 106.92, 116.11, 117.43, 117.59, 99.09, 100.67, 103.12, 105.02, 114.55, 99.11, 100.77, 103.18, 105.39, 115.97
There are no competitors who finished with a time less than 98.43 seconds. Therefore, the actual percentage of times less than 98.43 seconds is 0%. (Round to one decimal place as needed)Thus, option D is correct.c) The two percentages do agree.
This is because the Normal probability plot shows that the Normal model is not appropriate.
Therefore, the actual percentage of times less than 98.43 seconds is 0%, which is different from the percentage that was calculated using the Normal model. Since the Normal model is not appropriate, the actual percentage of times is more accurate.

Briefly discuss the difference between these two models and explain why the real estate should have its own asset allocation model.
The difference between the two models and why real estate should have its own asset allocation model.
The Sharpe ratio is a measure of risk-adjusted return. It is calculated by dividing the excess return of an investment over a benchmark by the standard deviation of the investment's returns. The higher the Sharpe ratio, the better the investment's risk-adjusted return.
The Cheng, Lin, and Liu model is a more complex model that takes into account the time horizon of the investment, the volatility of the investment, and the correlation between the investment and the benchmark. The model is designed to maximize the Sharpe ratio of the investment over a specified time horizon.
The real estate market is different from the financial market in several ways. Real estate is a illiquid asset, meaning that it can be difficult to sell quickly. Real estate is also a cyclical asset, meaning that its prices tend to go up and down over time. Real estate is also a heterogeneous asset, meaning that there is a wide variety of properties available, each with its own unique characteristics.
Because of these differences, the real estate market should have its own asset allocation model. A model that is designed for the financial market may not be appropriate for the real estate market. A real estate asset allocation model should take into account the illiquidity, cyclicality, and heterogeneity of the real estate market.
Here are some additional reasons why real estate should have its own asset allocation model:
Real estate is a long-term investment. The typical holding period for real estate is 10 years or more. This is different from the financial market, where the typical holding period is much shorter.
Real estate is a leveraged investment. This means that investors can use borrowed money to purchase real estate. This can magnify the potential returns of real estate, but it can also magnify the potential losses.
Real estate is a local investment. The value of real estate is often driven by local factors, such as the job market, the economy, and the demographics. This means that real estate investments should be tailored to the specific market in which they are located.
Overall, the real estate market is different from the financial market in several ways. These differences make it important for real estate investors to have their own asset allocation model.

Which symbol creates a true sentence? (14 – 8) ÷ 2 _____ 14 – 8 ÷ 2 > =
Answer:
>
Step-by-step explanation:
(14 – 8) ÷ 2 is equal to 3
14 – 8 ÷ 2 is equal to 10
The correct symbol in the relation is (14 – 8) ÷ 2< 14 – 8 ÷ 2.
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
For example, Olivia is selected in the 12U Softball.
How old is Olivia? You don't know the age of Olivia, because it doesn't say "equals". But you do know her age should be less than or equal to 12, so it can be written as Olivia's Age ≤ 12. This is a practical scenario related to inequalities.
Given:
(14 – 8) ÷ 2 _____ 14 – 8 ÷ 2
Now, solving both expression we have
(14 – 8) ÷ 2
= 6 /2
=3
and, 14 – 8 ÷ 2

Write the equation of the line in point-slope form. Show your work.
Write the equation of the line in slope-intercept form. Show your work
Answer:
see below
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 4-1)/(-2- -3)
= (4-1)/(-2+3)
= 3/1
= 3
Point slope form is
( y-y1)= m(x-x1)
using the first point
y-1 = 3( x--3)
y-1 = 3(x+3)
using the second point
y-4 = 3(x - -2)
y-4 = 3(x +2)
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 3x+b
Substituting a point into the equation
4 = 3(-2) +b
4 = -6 +b

What is the slope of a line perpendicular to the line y = 2x + 5?
A. 1/2
B. -2
C. 2
D. -1/2
Answer: A
Step-by-step explanation: You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.

In a 2-sample z-test for two proportions, you find the following: X1 = 24 n1 = 200 X2 = 17 my = 150 You decide
to run a test for which the alternative hypothesis is Hj: p1 > p2- Find the appropriate test statistic for the
test. Enter the test statistic - round to 4 decimal places. Z =
The appropriate test statistic for this test is approximately 0.2103 (rounded to 4 decimal places).
To find the appropriate test statistic for a 2-sample z-test for two proportions, we need to calculate the standard error and then use it to compute the z-score. The formula for the standard error is:
SE = sqrt[(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)]
Where p1 and p2 are the sample proportions, and n1 and n2 are the sample sizes.
In this case, we have the following values:
X1 = 24 (number of successes in sample 1)
n1 = 200 (sample size 1)
X2 = 17 (number of successes in sample 2)
n2 = 150 (sample size 2)
To calculate the sample proportions, we divide the number of successes by the respective sample sizes:
p1 = X1 / n1 = 24 / 200 = 0.12
p2 = X2 / n2 = 17 / 150 = 0.1133
Now, we can plug these values into the formula to calculate the standard error:
SE = sqrt[(0.12 * (1 - 0.12) / 200) + (0.1133 * (1 - 0.1133) / 150)]
SE ≈ 0.0319
Finally, the test statistic (z-score) is calculated by subtracting the two sample proportions and dividing by the standard error:
Z = (p1 - p2) / SE
Z = (0.12 - 0.1133) / 0.0319
Z ≈ 0.2103
Therefore, the appropriate test statistic for this test is approximately 0.2103 (rounded to 4 decimal places).

Jim is a furniture salesman. He can choose option A, a weekly pay of $300 plus 3.5% of his total sales or he can choose option B, to earn a flat rate of $550 for the week. Jim sells x dollars worth of furniture during the week
Jim should choose Option A preferable for sales above $7,142.86.
To determine which option is more advantageous for Jim, we can compare the earnings under each option based on Jim's total sales (x dollars).
Option A: Weekly pay of $300 plus 3.5% of total sales.
Earnings under Option A = $300 + 0.035x
Option B: Flat rate of $550 for the week.
Earnings under Option B = $550
To determine which option is more beneficial, we need to compare the earnings. If the earnings under Option A are higher than the earnings under Option B for a given value of x, then Option A is preferable. Otherwise, if the earnings under Option B are higher, then Option B is preferable.
Let's compare the two options for different values of x:
For Option A to be more advantageous:
$300 + 0.035x > $550
Simplifying the inequality:
0.035x > $550 - $300
0.035x > $250
Dividing both sides of the inequality by 0.035:
x > $250 / 0.035
x > $7,142.86
So, if Jim's total sales for the week (x) exceed $7,142.86, Option A would be more advantageous.
For values of x less than or equal to $7,142.86, Option B would be more advantageous.
It's important to note that this analysis assumes that Jim's earnings are solely based on either Option A or Option B, and there are no other factors or commissions involved in his compensation.
