The attached Excel file2013 NCAA BB Tournamentshows the salaries paid to the coaches of 62 of the 68 teams in the 2013 NCAA basketball tournament (not all private schools report their coach's salaries). Consider these 62 salaries to be a sample from the population of year 2013 salaries of all 346 NCAA Division I basketball coaches.

Question 1. Use the 62 salaries from the TOTAL PAY column to construct a90% confidence interval for the mean year 2013 salary of all basketball coaches in NCAA Division I.

________ lower bound of confidence interval

________ upper bound of confidence interval

Question 2. Coach Mike Krzyzewski's high salary is an outlier and could be significantly affecting the confidence interval results. Remove Coach Krzyzewski's salary from the data and recalculate the90% confidence interval using the remaining 61 salaries.

________ lower bound of confidence interval

_________ upper bound of confidence interval.
