Question

When 370 college students were surveyed,155 said they own their car. Find a point estimate for p, the population proportion of students who own their cars.

Answer 1

The point estimate is 0.4189

Explanation:

To answer the question, we note that the point estimate for the population mean is the sample mean and the point estimate used to estimate the population proportion is the sample proportion

Therefore, the point estimate p is the sample mean given by the following relation;

`Mean = (Number \ of \ required \ outcome)/(Number \ of \ possible \ outcome) = (Number \ of \ students \ who \ owned \ their \ cars)/(Number \ of \ college student \ surveyed)`

`\therefore \ The \ point \ estimate \ = The \ mean = (155)/(370) = 0.4189`

The point estimate = 0.4189.
