Think about a population mean that you may be interested in and propose a confidence interval problem for this parameter.

Think about a population mean that you may be interested in and propose a confidence interval problem for this parameter.

For example, to the problem is to estimate the population mean number of times that adults go out for dinner each week. The data could be that you spoke with seven people you know and found that they went out 2, 0, 1, 5, 0, 2, and 3 times last week. You then would choose to calculate a 95% (or another level) confidence interval for the population mean.
