To determine if the amount of money spent on alcohol increases as the semester continues, the same individuals were surveyed in august and in november. the amount that they spent on alcoholic beverages over one weekend in each of the months was compared. in this problem, we want to make inferences about:
a. one mean b. comparing means from dependent samples c. comparing means from 2 independent samples d. one proportion e. comparing proportions from 2 independent samples f. comparing proportions from dependent samples

b. comparing means from dependent samples

Step-by-step explanation:

First, it is not a proportion because the study wants to determine only the amount of money spent on alcohol, not a part of the salary or part of people's income.

The study wants to determine the mean amount of money people spent on alcohol. Because they want to know if this mean increases over time, they will compare the mean money spent in August with the mean money spent in November.

Both samples are dependent because same individuals were surveyed, then it is probable that the people who spent a lot of money in alcohol with will likely spent a lot of money in this on November. The same in the other way: people who do not spent much in alcohol in August (sample 1) will probably spent not much in this on November (sample 2).
