Question
The value of the z-score in a hypothesis test is influenced by a variety of factors. Assuming that all
other variables are held constant, explain how the value of z and the probability of rejecting the null hypothesis is influenced by each of the following:

b. Increasing the population standard deviation.
c. Increasing the number of scores in the sample
