Which of following is the range of proportions that is within one standard deviation of the sampling proportion mean when the standard deviation 0.02 and the mean is 0.22

Answer 1

The range of proportions that is within one standard deviation of the sampling proportion mean would be 0.20 to 0.24.

This can be calculated by subtracting and adding one standard deviation (0.02) from the mean (0.22):

0.22 - 0.02 = 0.20
0.22 + 0.02 = 0.24

So, the range is 0.20 to 0.24.
