Two samples are selected from a population, and a treatment is administered to the samples. If both samples have the same mean and the same variance, you are more likely to find a significant treatment effect with a sample of n = 100 than with a sample of n = 4.
True, two samples are selected from a population, and a treatment is administered to the samples. If both samples have the same mean and the same variance, you are more likely to find a significant treatment effect with a sample of n = 100 than with a sample of n = 4.
What is the mean?The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.
Given:
Two samples are selected from a population, and a treatment is administered to the samples.
If both samples have the same mean and the same variance.
That means, they have the same t statistic.
A t-test compares the average values of two data sets and determines if they came from the same population.
You are more likely to find a significant treatment effect with a sample of n = 100 than with a sample of n = 4.
Because the value of t-test are same.
Therefore, the statement is true.

A banker has an annual income of $75,234. The income tax she has to pay is 7%. What is the amount of income tax the banker has to pay?
(NUMBERS ONLY NO $ SIGN NO COMMA)
A banker has an annual income of $75,234. The income tax she has to pay is 7%. What is the amount of income tax the banker has to pay?
Solution:To solve the problem, we need to use the formula. P = B × R
Percentage = Base × RateP = B × RP = 75,234 × 7%P = 75,234 × 0.07P = 5,266.38Answer:Therefore, the amount of income tax the banker has to pay is 5,266.38.The triangle inequality Theorem states that the sum of the lengths of any two sides of the triangle is greater than the length of the third slide. The lengths of two sides of a triangle are 14ft and 27ft. Find the possible lengths of the third side
The third slide must have a length greater than __ft and less than _ft
Answer:
12 < x < 42 or x | ( 12,42 ) ft.
Step-by-step explanation:
15 + 27 = 42; 27 − 15 = 12 . Therefore the third side must be
less than 42 ft ant greater that 12 ft. Therefore possible length
of third side of size x is 12 < x < 42 or x | ( 12,42 ) ft [Ans]

The tangent of the curve f(t) =2+nt+mt^2 at point (1,1/2) is parallel to the normal g(t)= t^2+6t+13(-2,2), calculate the values m and n.
Step-by-step explanation:
The slope of g(t) as (-2,2) is given by
[tex]g'(t)=2t+6[/tex]
[tex]g'(-2)=2(-2)+6=2[/tex]
Since the normal is parallel to the tangent of f(t) at (1, 1/2),
The tangent line of f(t) has a slope of
[tex]\dfrac{d}{dx}f(t)=n+2mt=2[/tex]
At point (1, 1/2), we know
[tex]f'(1)=n+2m=2[/tex]
[tex]f(1)=2+n(1)+m(1)^2=2+n+m=\frac12[/tex]
Solving,
[tex]n=5, m=-\frac72[/tex]

What is the equation of the line in point-slope form and slope-intercept form that is
perpendicular to the line
4x - 3y = 30 and passes through the point (-8, 7)?
9514 1404 393
Answer:
y -7 = -3/4(x +8)y = -3/4x +1Step-by-step explanation:
The slope of a line in the form ...
ax +by = c
is ...
m = -a/b
So, the slope of the given line is ...
-4/(-3) = 4/3
The slope of the perpendicular line is the opposite reciprocal of this,
m' = -1/(4/3) = -3/4
__
The point-slope equation of a line is ...
y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)
Then your perpendicular line with slope -3/4 through point (-8, 7) is ...
y -7 = -3/4(x +8)
Rearranging to slope-intercept form, we get ...
y = -3/4x -3/4(8) +7
y = -3/4x +1

Find the values of the numbers a and b.
Answer:
Step-by-step explanation:
There appears to be a problem with your equation as it can be reduced to
y = (a + b)x + 3
which is a line of slope (a + b) and y intercept of 3
plugging in our points
10 = -1(a + b) + 3
7 = -1(a + b)
a + b = -7
13 = 2(a + b) + 3
10 = 2(a + b)
a + b = 5
a + b cannot equal both 5 and -7 at the same time.
I will GUESS that you mean y = ax² + bx + 3
10 = a(-1)² + b(-1) + 3
10 = a - b + 3.
b = a - 7
13 = a(2)² + b(2) + 3
13 = 4a + 2b + 3
10 = 4a + 2b
10 = 4a + 2(a - 7)
10 = 4a + 2a - 14
24 = 6a
a = 4
b = 4 - 7
b = -3

A bag is filled with green and blue marbles. There are 41 marbles in the bag. If there are 15 more green marbles than blue marbles, find the number of green marbles and the number of blue marbles in the bag.
Find the solution by setting up an equation. You have two choices for how you will pick your variable. For each of the following variable choices, write an equation (just set up the equation, do not solve it yet) that describes the relationship between the number of green marbles, the number of blue marbles, and the total number of marbles in the bag:
there will be 26 blue marbles

What is the range of the following function?
Answer:
[tex][-5,5][/tex]
Step-by-step explanation:
The range is the y-axis, and the endpoints are filled in, so we put brackets.
Side note:
This is called Interval Notation. This is very important when you ask for the domain and range of functions (domain is for the x-axis). You will see this system A LOT, so you have to get used to the name and the language Interval notation uses.
