*Instructions: In testing situations, carry out a two-tailed test and use a p-value threshold of 5% unless explicitly directed otherwise.

Consider the following changes that might occur in the context of carrying out either a one or two sample z test. For each, first answer:

Will we be MORE likely or LESS likely to reject the null hypothesis if this happens? Then explain your answer.

A) if the sample size gets bigger in a one-sample z test

B) if the standard deviation of the box gets smaller in a one-sample z test

C) if the observed value of the statistic gets closer to the value in the null hypothesis in a one-sample z test

D) if the difference between the two statistics in a two-sample z test gets bigger

E) if we use a lower threshold for the p-value (e.g. 1% instead of 5%)
