Final answer:
The sample proportion, p, of college students who own shares of stock can be determined by calculating the ratio of the number of college students who own shares of stock to the total sample size of college students.
Step-by-step explanation:
The sample proportion, p, of college students who own shares of stock can be determined by calculating the ratio of the number of college students who own shares of stock to the total sample size of college students. In this case, we are given the responses (Y for yes and N for no) from a sample of 20 college students. Let's say 12 students responded with Y and 8 students responded with N. Therefore, the sample proportion of college students who own shares of stock is 12/20 or 0.6.
