Question

Determine 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. Assume the grade point average of the 125 students has a mean of p=2.7. O A. -0.7 OB. -0,07 O C. 2.35 OD. 1.65​

Answer 1

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.
