Question: Use data from problem 19 of Ch. 17 of KKNR (ex1719_XXX.dat, where XXX is your Individual Data Set Number from Blackboard) from the Best Mutual

Use data from problem 19 of Ch. 17 of KKNR (ex1719_XXX.dat, where XXX is your Individual Data Set Number from Blackboard) from the "Best Mutual Funds" of 1996 from U.S. News & World Report. Variables in this dataset (in order) are: fund,cat (fund category: 1 = Aggressive growth, 2 = Long-term Growth, 3 = Growth and income, 4 = income),load (N = no load, L = load),vol (volatility: letter grade from A+ to F, with A+ = least volatile and F = most volatile),OPI (Overall Performance Index; higher is better). See textbook for more details.

  1. (P) Create and apply a format that will appropriately identify the 4 levels of the fund category [cat] variable (Hint: See Lab 2). Also create meaningful labels for the OPI and cat variable. The labels/formatting will improve the readability of the boxplot below.

  1. (P, O)Create a boxplot of OPI by fund category. Make sure the mean is plotted for each group. (Hint: To allow the names of the 4cat variable levels to be fully printed, create a horizontal boxplot. Do this by: (1) turning on ODS graphicsif not already onand (2) using theHORIZONTAL option in theBOXPLOT statement.)

  1. (W, P, O)In a small table, report the sample size, mean, standard deviation, minimum, and maximum of OPI for each fund category group. Comment on whether the standard deviations are similar across groups.

  1. (W) In the context of this problem, write three forms of the one-way ANOVA model, along with the corresponding null and alternative hypotheses.

  1. (P, O)Use SAS to perform an ANOVA and to obtain both Tukey's and Scheff's tests for multiple pairwise comparisons.

  1. (W) Summarize your conclusions..
