Step 1
Given that there are 110 people in the sample and I get a 95% confidence interval of (4, 6) in minutes.
This means I am 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 95% of the values.
Step 2
Answer:
1. 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 95% sure your sample resulted in a confidence interval the contains the true mean -True
