a. Determine the sample proportion, p, of college students who own shares of stock.

Answer 1

The sample proportion p of college students who own shares of stock is 27.5%, calculated by dividing the number of students who responded 'Y' (11) by the total number of students surveyed (40).

Step-by-step explanation:

To determine the sample proportion p of college students who own shares of stock from the provided data, we count the number of 'Y' responses and divide by the total number of students surveyed, which is 40. Counting the 'Y' responses, we find there are 11 students who own stock out of the 40 surveyed. Therefore, the sample proportion p is calculated as 11/40 = 0.275 or 27.5%.
