Answer 1

We want to make inferences about whether the amount of money spent on alcohol increases as the semester continues.

Step-by-step explanation:

In this problem, we want to make inferences about whether the amount of money spent on alcohol increases as the semester continues. To test this, the same individuals were surveyed in August and in November, and the amount they spent on alcoholic beverages over one weekend in each month was compared. By comparing the two sets of data, we can determine if there is a statistically significant difference in the amount of money spent on alcohol between the two time periods.

Answer 2

Options for the question:

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

Answer:

b. comparing means from dependent samples

Step-by-step explanation:

The samples are dependent as same individuals are sampled over the months(August and November). Therefore individuals sampled in August will likely show some of the same traits in November. Also we are comparing means since we are working with mean of alcohol consumed for each period and then comparing with another period/months.
