Question

Think about a population mean that you may be interested in and propose a confidence interval problem for this parameter. Your data values should be approximately normal.

For example, you may want to estimate the population mean number of times that adults go out for dinner each week. Your data could be that you spoke with seven people you know and found that they went out 1, 4, 2, 3, 2, 0, and 5 times last week. You then would choose to calculate a 95% (or another level) confidence interval for the population mean.

Assume a random sample was chosen, which is required to determine a confidence interval.

Think about a population mean that you may be interested in and
propose a hypothesis test problem for this parameter.
For example, you may believe that the population mean number of
times that adults go out for dinner each week is less than 1.5.
Your data could be that you spoke with 7 people and found that they
went out 1, 0, 1,3, 4, 1, and 1 times last week. You then would
choose to test this hypothesis at the...
