Step 1

Given that there are 110 people in the sample and I get a 95% confidence interval of \(\displaystyle{\left({4},\ {6}\right)}\) in minutes.

This means I am \(\displaystyle{95}\%\) sure that my sample resulted in a confidence interval the contains the true mean of the population.

This does not mean a range that contains \(\displaystyle{95}\%\) of the values.

Step 2

Answer:

1. \(\displaystyle{95}\%\) of people wait between 4 and 6 minutes at the restaurant - False

2. 95 of the people in your sample waited between 4 and 6 minutes - False

3. You are \(\displaystyle{95}\%\) sure your sample resulted in a confidence interval the contains the true mean -True
