Consider an x distribution with standard deviation o = 12. (For each answer, enter an exact number)

a) If specifications for a research project require the standard error of the corresponding
x̅ distribution to be 4, how large does the sample size need to be?

n =

b) If specifications for a research project require the standard error of the corresponding x̅ distribution to be 1. How large does the sample size need to be?

n =
