The standard error of the mean:
 a. is never larger than the standard deviation of the population.
  b. decreases as the sample size increases.
  c. measures the variability of the mean from sample to sample.
  d. All of these choices are true.

Question 2

In simple linear regression, most often we perform a two-tail test of the population slope 1 to determine whether there is sufficient evidence to infer that a linear relationship exists. The null hypothesis is stated as:
 a. H0: 1 = 0
  b. H0: 1 = b1
  c. H0: 1  0
  d. None of these choices.
