The average American consumed 10.6 pounds of mozzarella cheese in 2009 (U.S. Department of Agriculture, February 20, 2012). Do male and female consumers differ in the amounts of mozzarella cheese they consume? The average consumption in a survey of 50 male consumers was 13.1 pounds, and the average consumption in a survey of 35 female consumers was 8.6 pounds. What is the point estimate of the difference between the population mean consumption for males and the population mean consumption for females?

Select one:

Expert Solution

The average American consumed 10.6 pounds of Mozzarella cheese in 2009.

The average consumption in a survey of 50 male consumers was 13.1 pounds.

The average consumption in a survey of 35 female customers was 8.6 pounds.

We have to find the point estimate of the difference between the population mean consumption for males and the population mean consumption for females.

So, basically we have to find the point estimate for

when

is given.

Now, we know that

We use as the point estimate of .

So, the point estimate of

is .

So, the point estimate is

So, the answer is option (a) 4.5.
