Question: i want to estimate the population mean number of times...

Question details

I want to estimate the population mean number of times that adults go to the movie each week. I spoke with seven people I know and found that they went out 2, 0, 1, 5, 0, 2, and 3 times last week. I want to calculate an 80% confidence interval for the population mean.

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