An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use %B= 0.05. Factor A is method of loading and unloading; Factor B is the type of ride.

WE will consider differences as (New – Old).
From given data, we have
Dbar = 0.70
SD = 0.70
n = 5
Degrees of freedom = df = n – 1 = 5 – 1 = 4
Test statistic = t = (Dbar - µd) /[SD/sqrt(n)]
t = (0.70 – 0)/[0.70/sqrt(5)]
t = 0.70/ 0.3130
t = 2.2361
Critical value = 2.1318
(by using t-table)
P-value = 0.0445
(by using t-table)
P-value < α = 0.05
So, we reject the null hypothesis
There is sufficient evidence to conclude that the average monthly sales revenue increases after the advertising.
Kindly check the first attached image for the graphical table.
Part b
P-value = 0.0445
α = 0.01
P-value > α = 0.01

Galen sold tickets for his church’s carnival for a total of $2,820. Children’s tickets cost $3 each and adult tickets cost $5 each. The number of children's tickets sold was 30 more than 3 times the number of adult tickets sold. How many children’s tickets and how many adult tickets did he sell?
Answers
Answer:
a = 195 ; c = 615
Step-by-step explanation:
So, you want to start by forming your equations...
I will use 'c' for children and 'a' for adults for my variables
3a + 30 = c
(this is because of the info that 30 more tickets than 3 times the amount of children's were sold than adult)
then for equation 2:
3c + 5a = 2820
(this is because of the prices of the tickets and the total money raised)
Then, plug in the equation for c
Your equation should look like:
3(3a + 30) + 5a = 2820
You get:
(9a +90) + 5a = 2820
Then:
14a = 2730
So:
a = 195 adult tickets sold
Plug in a, to find c:
3 (195) + 30 = c
585 + 30 = c
c = 615 children tickets sold

Probability = 0.25.
Step-by-step explanation:
The Important thing to note here is that we have sixteen(16) different possible outcomes for this particular problem or question.
From the question above, we are given the following information or data: ''bag contains four chips of different colors, including red, blue, green, and yellow. A chip is selected at random from the bag and then replaced in the bag. A second chip is then selected at random"
Hence, the sixteen (16) different possible outcomes are; RR, RB, BB, BR, RG, GR, GG, RY, YR, YY, BG, GB, BY, YB, GY, YG.
To calculate the probability we need to used the numbers of f different colors divided by the number big possible outcomes, that is; 4/16 = 0.25.
Probability that one blue chip and one yellow chip are selected is 1/8
Given that a bag contains four chips of different colors
The colors given are red , blue, green and yellow
A chip is selected at random from the bag and replaced in the bag
After that a second chip is selected at random.
In both the selections there is a equal probability of choosing any color chip at random
So for the first chip the color can be either blue , green red or yellow.
Similarly for the second chip the color of the chosen chip can be either blue , green , red or yellow
We can make set of possible outcomes for the colors of chips in the first and the second draw
The number of possible outcomes are 16 in numbers
{ RR, RB, RG, RY. BR, BB, BG, BY, GR,GB, GG, GY, YR, YB, YG, YY}
Probability that one blue chip and one yellow chip are selected is 1/8
Since there is only two such case.

Score data from a statewide exam for 10th-graders follows a normal distribution, has a mean of 77, and has a standard deviation of 6.5. According to the Empirical Rule, 34% of test scores fall into what range? Select all that apply.
Answers
Given Information:
Mean test score = μ = 77
Standard deviation of test score = σ = 6.5 seconds
Answer:
The lower limit represents those 34% test scores which are below the mean test score.
The range of test scores will be (70.5 to 77)
The upper limit represents those 34% test scores which are above the mean test score.
The range of test scores will be (77 to 83.5)
Step-by-step explanation:
Normal Distribution:
We are given a Normal Distribution, which is a continuous probability distribution and is symmetrical around the mean. The shape of this distribution is like a bell curve and most of the data is clustered around the mean. The area under this bell shaped curve represents the probability.
The Empirical Rule:
The empirical rule states that approximately 68% of all the data lie within 1 standard deviation from the mean, approximately 95% of all the data lie within 2 standard deviations from the mean and approximately 99.7% of all the data lie within 3 standard deviations from the mean.
68% of all the data lie within 1 standard deviation from the mean, so that means 34% (half of 68%) of the test scores will be below the mean test score and remaining 34% of the test scores will be above the mean test score.
The confidence interval is given by
[tex]CI = \mu \pm 1 \cdot \sigma \\\\CI = 77 \pm 1 \cdot (6.5) \\\\CI = 77 \pm 6.5 \\\\Lower \: limit = 77 - 6.5 = 70.5 \\\\Upper \: limit = 77 + 6.5 = 83.5 \\\\[/tex]
The lower limit represents those 34% test scores which are below the mean test score.
So the range of test scores will be (70.5 to 77)
The upper limit represents those 34% test scores which are above the mean test score.
So the range of test scores will be (77 to 83.5)

Answer:
A
Step-by-step explanation:
Suppose p = 6 and b = 8, so that tan x is 6/8
Then the hypotenuse is sq rt (6x6 + 8x8) = sq rt (36 + 64) = sq rt (100) = 10
So sin x = p / h = 6 / 10
And cos x = b / h = 8 / 10
So A is the answer
Answer:
A. sin x = 6/10 and cos x = 8/10.
Step-by-step explanation:
If tan x is 6/8 the opposite side to x = 6 and the adjacent side = 8.
So the hypotenuse of the triangle = √(6^2 + 8^2)
= √100
= 10.
So sin x = 6/10 and cos x = 8/10.
