9. A statistician employed by a television rating service wanted to determine if there were differences in television viewing habits among three different cities in California. She took a random sample of five adults in each of the cities and asked each to report the number of hours spent watching television in the previous week. The results are shown below. Hours Spent Watching Television San Diego Los Angeles San Francisco 25 28 23 31 33 18 18 35 21 23 29 17 27 36 15 a) Set up the ANOVA Table. Use a = 0.05 to determine the critical value. b) Can she infer at the 5% significance level that differences in hours of television watching exist among the three cities (i.e. Perform the Hypothesis testing)? c) Apply Fisher's LSD method and also Tukey's method to determine which cities in California will differ in TV viewing habits.

The Interpersonal Reactivity Index is a survey designed to assess four different types of empathy. One type of empathy, called Empathetic Concern, measures the tendency to feel sympathy and compassion for people who are less fortunate. The index ranges from 0 (less empathetic) to 28 (more empathetic). The following data, representing random samples of 8 males and 8 females, are consistent with results reported in psychological studies. Boxplots show that it is reasonable to assume that the populations are approximately normal and have equal variances. Males 13 20 14 16 13 26 21 23 Females 22 20 26 25 28 24 16 19 Can you conclude that there is a difference in mean empathy score between men and women? Use a=0.03.
