Question

When 475 junior college students were​ surveyed, 110 said that they have previously owned a motorcycle. Find a point estimate for​ P, the population proportion of students who have previously owned a​ motorcycle, rounding to three decimal places.

a) 0.232
b) 0.316
c) 0.578
d) 0.682

Answer 1

To find the point estimate, divide the number of students who have previously owned a motorcycle by the total number of students surveyed. The point estimate is approximately 0.232.

Step-by-step explanation:

To find the point estimate for the population proportion of students who have previously owned a motorcycle, we divide the number of students who have previously owned a motorcycle by the total number of students surveyed. In this case, the number of students who have previously owned a motorcycle is 110, and the total number of students surveyed is 475. So the point estimate is:

Point estimate = Number of students who have previously owned a motorcycle / Total number of students surveyed
Point estimate = 110 / 475
Point estimate ≈ 0.232

Therefore, the point estimate for the population proportion of students who have previously owned a motorcycle is approximately 0.232.
