# Question

Explain whether each of the following is possible.

a. A relationship exists in the observed sample but not in the population from which the sample was drawn.

b. A relationship does not exist in the observed sample but does exist in the population from which the sample was drawn.

c. A relationship does not exist in the observed sample, but an analysis of the sample shows that there is a statistically significant relationship, so it is inferred that there is a relationship in the population. Exercises 28 to 33 are based on News Story 2, “Research shows women harder hit by hangovers” and the accompanying Original Source 2. In the study, 472 men and 758 women, all of whom were college students and alcohol drinkers, were asked about whether they had experienced each of 13 hangover symptoms in the previous year.
