Answer:
-15
Step-by-step explanation:
Answer:
The standard error for the sampling distribution is 1.323.
Step-by-step explanation:
Let <em>X</em> = scores of girls and <em>Y</em> = scores of boys.
The information provided is:
As the population standard deviations are not known, use a pooled standard deviation to estimate the standard error of the sampling distribution.
The formula of pooled standard deviation is:
Compute the standard error for the sampling distribution as follows:
Thus, the standard error for the sampling distribution is 1.323.
Best to take this in two parts.
1, find the factors of 36:
1 and 36
2 and 18
3 and 12
4 and 9
6 and 6
2, Now, using those, add the factors and see which add up to 15... in this case, that would be 12 and 3!
Answer:
Try B) 2x - 3y = -9
Step-by-step explanation:
I plotted the points and started to make each answer into the "y = " formula. The only one that passed through all the points was B) 2x - 3y = -9 which I changed into y = 2x/3 + 3
Answer:
1.04167
Step-by-step explanation:
Z -score formula is given as
z = (x-μ)/σ, where
x is the raw score = 74
μ is the population mean = 69
σ is the population standard deviation = 4.8
Z score = x - μ/ σ
= 74 - 69/4.8
= 1.04167
The z score for a person is given as 1.04167
