Question

Overweight Men For a random sample of 70 overweight men, the mean of the number of pounds that they were overweight was 29. The standard deviation of the population is 4.1 pounds.

(a) The best point estimate of the mean is pounds.

Answer 1

The best point estimate of the mean is 29 pounds.

Step-by-step explanation:

The best point estimate of the mean is 29 pounds.

A point estimate is a single value that is used to estimate an unknown population parameter. In this case, the unknown population parameter is the mean number of pounds that overweight men are overweight.

To estimate this parameter, we use the sample mean, which is calculated by taking the average of the number of pounds that the 70 overweight men in the sample were overweight. This sample mean is equal to 29 pounds.
