Question

A state meat inspector in Iowa has been given the assignment of estimating the mean net weight of packages of ground chuck labeled "3 pounds." Of course, he realizes that the weights cannot be precisely 3 pounds. A sample of 36 packages reveals the mean weight to be 3.01 pounds, with a standard deviation of 0.03 pound. What is the estimated population mean?

Answer 1

Answer: 3.01

Explanation:

We know that is the population mean unknown , then the sample mean
`(\overline{x})` is the best point estimate for population mean
`\mu`.

Let
`\mu` be the population mean weight of packages of ground ground chuck labeled "3 pounds."

Given : A sample of 36 packages reveals the mean weight to be 3.01 pounds.

i.e. sample mean = 3.01

Then, the estimated population mean should be 3.01.

Hence, the estimated population mean= 3.01
