Homework 9
1. Refer to DOGS1 data. The investigator may want to ensure that the dogs allocated to each treatment group were of similar compositions with respect to gender and hair coat. Use PROC FREQ to conduct Fisher’s exact test to see if the concentration of the drug received was statistically independent of the gender of the dog. Likewise, see if the length of the coat and the drug treatment were statistically independent with Fisher’s exact test. Write your interpretation of the results of these tests.

2. Refer to the MANATEES data. Your task is to see if the proportion of manatees killed by human-related causes has remained about the same through time or if this proportion has changed significantly from year to year. Create a dataset with …show more content…
When the defendant was black and the victim was white, in what percentage of cases was the death penalty verdict given?
d. When the races of the victim and the defendant were the same, in what percentage of cases was the death penalty given?

7. Refer to HOCKEY data. Did Ohio State have a home-ice advantage? Use PROC FREQ to perform Fisher’s exact test for the 2x2 table of the outcome of the game (“won” or “lost or tied”) versus location (Columbus, Ohio or elsewhere). Don’t forget to change the score of the final game to Boston College 5, Ohio State 2.

8. Refer to the HANKS data. Your task is to use a SAS program to count the number of movies in which Tom Hanks appeared in each of the years from 1984-1998, then make a scatterplot with the number of movies made in each year on the vertical axis versus the year on the horizontal axis. In some years, such as 1997, he did not appear in any movies. On the scatterplot, indicate those years by plotting a point at zero. To do this you could create another dataset with all of the years from 1984-1998 by using a Do loop, then MERGE that dataset with the dataset containing the movie counts. Then, you will need to replace missing values for movie counts with
