Suppose a population has a mean of 7 for some characteristic of interest and a standard deviation of 9.6. a sample is drawn from this population of size 64. what is the standard error of the mean? a. 1.2 b. 0.7 c. 3.3 d. 0.15

 A. 1.2

Step-by-step explanation:

Given : Sample size : n= 64

Standard deviation:

The formula to find the standard error of mean is given by :-

Therefore, the standard error of the mean= 1.2

Hence, A is the right option.
