Answer #1

True or False: Null and Alternative Hypotheses can never refer to sample statistics.

Answer: True, because Null and Alternative Hypotheses are always refer to the population parameters.

True or False: Type I error and Type II error can both be controlled by increasing the sample size.

Answer: True, because type I error or type II error can be controlled by either increasing the sample size or decreasing the alpha value while assuming all other factors constant.

True or False: The pooled variance t-test can never be used when you have dependent sampling.

Answer: True, because the pooled variance t-test used in dependent samples t test and not in dependent samples t test. We use the difference in the dependent samples t test and so pooled variance is not possible in this case.
