If other factors are held constant,which set of sample characteristics is most likely to reject a null hypothesis stating that m = 80?​
A)​M = 85 and small sample variance
B)​M = 85 and large sample variance
C)​M = 90 and small sample variance
D)​M = 90 and large sample variance

A larger sample mean (M = 90) than the null hypothesis value of 80 is more likely to reject the null hypothesis. However, a small sample variance may make the results less reliable. Therefore, choice C (M = 90 and small sample variance) is the most likely set of characteristics to reject the null hypothesis.
