statistically compare and test equivalence of average (mean) stock returns for the two time periods (see attached handout).

Step 3: Convert the daily stock prices into daily returns. Please see attached handout for details.

Step 4: Summarize the higher moments in a table for the two time periods.

Step 5: Analyze your summary findings for the two time periods and submit.

a) statistically compare and test equivalence of average (mean) stock returns for the two time periods (see attached handout). Do keep in mind that stock prices could be going up or down (trending in any direction), what we are testing is “Did average stock returns for an investor differ significantly between the two time periods?”

b) compare higher moments included in your summary table for the two time periods
