1. A researcher wants to know if there is a difference in the proportion of men and women who often or sometimes feel free to report problems in the workplace.

Assume the p-value is 0.023. Interpret this p-value with an alpha level of 0.05.

Group of answer choices

a. With our given p-value, there is not enough statistically significant evidence that there is a difference in sample proportions of men and women who feel free "often" or "sometimes" to report workplace problems.

b. With our given p-value, there is enough statistically significant evidence that there is a difference in population proportions of men and women who feel free "often" or "sometimes" to report workplace problems.

c. With our given p-value, there is not enough statistically significant evidence that there is a difference in population proportions of men and women who feel free "often" or "sometimes" to report workplace problems.

d. With our given p-value, there is enough statistically significant evidence that there is a difference in sample proportions of men and women who feel free "often" or "sometimes" to report workplace problems.

2. In addition to year-round offerings, many breweries also produce special seasonal beers. One brewer at a local brewery was wondering if there was a relationship between someone's favorite type of beer, and their favorite season of the year. He decided to ask 100 people both what their favorite type of beer was (lager, stout, IPA, or red ale) and what their favorite season of the year was (spring, summer, fall, or winter).

What would be the degrees of freedom for this scenario?
