Question

1. You will need your ticker code (show your ticker code on your homework and include a printout of the data!) for stock prices for this question. Use your ticker code to obtain the closing prices for the following three time periods to obtain three data sets:

March 2, 2019 to March 16, 2019 Data set A

March 17, 2019 to March 31, 2019 Data set B

April 1, 2019 to April 17, 2019 Data set C

Data set A: 70.95, 71.58, 71.27, 70.61, 69.36, 69.68, 70.05, 70.10

Data set B: 71.14, 71.68, 71.93, 72.56, 72.26, 72.60, 73.26, 73.04

Data set C: 74.26, 74.56, 74.63, 74.65, 75.33, 75.50, 75.42, 75.78

Use the Bonferroni-Holm (regardless of whether part “a” is significant or not) to examine all pairwise comparisons. Show all your calculations and state your conclusions.
