Answer: huh ?
Step-by-step explanation:
The sampling error if the grade point averages for 10 randomly selected students from a class of 125 students has a mean of x =2. is A. -0.7.
Given:
Random number=10
mean of x=2
population=125
mean of p=2.7
Using this formula
Sampling error=x− μ
Where:
x= sample mean=2
μ=population mean=2.7
Let plug in the formula
Sampling error=2-2.7
Sampling error=-0.7
Inconclusion the sampling error is A.-0.7.
