A study on exercise habits used a random sample of 2,540 college students (1,220 females and 1,320 males). The study found the following: 818 of the females in the sample exercise on a regular basis. 924 of the males in the sample exercise on a regular basis. The average time that the 1742 students who exercise on a regular basis (818 + 924) spend exercising per week is 4.2 hours.
What is the point estimate for the average amount of time regular exercisers exercise?
Homework Answers
The point estimate of population mean is the sample mean.
In this case, average time that a sample of students who exercise on a regular basis spend exercising per week is 4.2 hours
So, the point estimate for the average amount of time regular exercisers exercise is also equal to 4.2 hours.

A study was done by researchers at a university to determine the percentage of all college students that exercise at least once per week. The study found that 411 students reported exercising at least once per week out of 800 surveyed.
