Show your work for all answers and include a printout of the data. Full credit will not be given to answers without work, and partial credit may be given when work is shown. Write any written answers or explanations clearly, and be as neat as possible. DUE first 10 minutes of class on Monday, November 21, 2016 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, 2016 to March 16, 2016 March 17, 2016 to March 31, 2016 April 1, 2016 to April 17, 2016 Data set A Data set B Data set C To ensure equal sample size per group use only the first 8 observations in each data set. Add 0.2 and 0.4 to each one of the closing prices in data sets B and C, respectively Imagine you are testing for the effects of two experimental drugs (data sets B and C) relative to a control group (Data set A) on a physiological variable. a) Conduct an ANOVA on the data set. Show all calculations, table of results, and state your conclusion. b) Use the Bonferroni-Holm to examine all pairwise comparisons. Show all you calculations and state your conclusions. (See next page for problem 2!) 2. The table below contains data on the enzyme activity of mannose-6-phosphate isomerase (MPI) for three different genotypes (SS, FS, FF) in the amphipod crustacean Platorchestia platensis. Because the effects of sex are not known, specimens were classified by sex. Conduct a two-way ANOVA on this dataset. Test for effect of genotype, the effect of sex, and whether there is an interaction effect between two factors. Show all calculations and state your conclusions. Replace the letters A-B-C-D-E-F in the table with the last six numbers of your student ID number SS Females 3.6A 2.89 3.22 2.74 3.16 Males 2.8D 3.41 3.21 3.11 3.13 FS 3.5B 4.29 3.34 3.25 3.51 3.6E 3.47 3.15 3.69 3.70 FF 4.8C 4.26 5.89 4.18 4.87 4.9F 3.98 5.18 4.88 4.92
