Problem 2

Problem 2 {S+2+4 = 11 points} A study of the effects of exercise on physiological and psychological variables compared tour group of male subjects. The treatment group {T} consisted of 1D participants in an exercise program. A control group {C} of 5 subjects volunteered for the program but were unable to attend the exercise program for various reasons. Subjects in the other two groups were selected to be similar to those in the rst two groups in age and other characteristics. These were 11 joggers {J} and 10 sedentary people {S} who did not regularly exercise. One of the variables measured at the end of the program was a physical tness score. Here is part of the ANGUA table for these data: Table 2.1 ANDVA Source of Degrees of 'v'ariance freedom Sum of Squares Mean Square F Between Groups 3 104 355.8? Within Groups 32 TD 5131.59 Total a. Fill in the missing entries in the ANDVA table. b. State HE. and H3 for this experiment. c. What is the distribution of the F statistic under the assumption that HE. is true? Give an approximate Pvalue for the ANDVA test. Write a brief conclusion. {If you couldn't calculate the value of F, take 9.35 as an answer.}
