1-Define the parameter, , that a confidence interval for the mean match length would be estimating.

2-Construct a 95% confidence interval for the population mean length of men's singles matches during Wimbledon. Show your calculations and round your final answer to two decimal places.Note: Show your values plugged into the formula using the "insert > equation" option above your text box. Also, be sure to state the critical t value.

3-Interpret your 95% confidence interval.

4-Does the confidence interval you computed represent an estimate for the population mean length of men's singles matches duringall professional tennis tournaments? Explain.

5-Suppose instead you wished to construct a 99% confidence interval for the population mean length of men's singles matches during Wimbledon with a margin of error of no more than 10 minutes. What is the minimum sample size required? Show all values plugged into the formula and remember to give your final answer as an integer value.
