The value of the z-scores 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 is influenced by each of the following: (Hint: When coming up with your answer, consider how changing the corresponding value in the z formula would change things if its value was increased by 10, 100, 1000, etc. while all other values constant.)

Increasing the difference between the sample mean and the original population mean will result in a(n) (increase/decrease) in the absolute value of z, and a(n) (increase/decrease) in the probability of obtaining a sample with that mean.

Increasing the population standard deviation will result in a(n) (increase/decrease) in the absolute value of z, and a(n) (increase/decrease) in the probability of obtaining a sample with that mean.

Increasing the number of scores in the sample will result in a(n) (increase/decrease) in the absolute value of z, and a(n) (increase/decrease)in the probability of obtaining a sample with that mean.
