Using the Retirement funds spreadsheet, please determine if there is a significant difference between the average 3 year rate of return on Large Growth and Large Value stock funds.

1. Write a null and alternative hypothesis statement for the appropriate hypothesis test.

2. At the 95% significance level, is there significant evidence of a difference between fund rate of returns for Large Value stock funds and Large Growth stock funds? Be sure to include if you are rejecting or not rejecting the null hypothesis.

3. Based upon your results above, provide a paragraph (3-4 sentence) conclusion that would be appropriate to explain the results to a senior executive that isn't as familiar with statistics as you are! Explain why senior executives would want to know these results.
