If other factors are held constant, which set of sample characteristics is most likely to reject a null hypothesis stating that $\mu$ = 80?
A)M = 85 for a sample of n = 25
B)M = 85 for a sample of n = 100
C)M = 90 for a sample of n = 25
D)M = 90 for a sample of n = 100

A larger sample size and a larger difference between the sample mean (M) and the hypothesized population mean ($\mu$) increase the likelihood of rejecting the null hypothesis. Option D has both a larger sample size (n = 100) and a larger difference (M = 90) compared to the hypothesized mean ($\mu$ = 80).
