Step-by-step explanation:
Hello,
f(x)=4(x+3)-5=4x+12-5=4x+7
y=4x+7==>c=(y-7)/4

Answer D
Answer:
The standard deviation of the sample mean differences is _5.23_
Step-by-step explanation:
We have a sample of a population A and a sample of a population B.
For the sample of population A, the standard deviation is
The sample size is:
.
For the sample of population B, the standard deviation is
The sample size is:
.
Then the standard deviation for the difference of means has the following form:
Finally
