Heart Rate and Exercise Exercise 11.60presented data (data set EX1160) on the heart rates forsamples of 10 men randomly selected from each offour age groups. Each man walked a treadmill at afixed grade for a period of 12 minutes, and theincrease in heart rate (the difference before and afterexercise) was recorded (in beats per minute). The dataare shown in the table.1019 2039 4059 606929 24 37 2833 27 25 2926 33 22 3427 31 33 3639 21 28 2135 28 26 2033 24 30 2529 34 34 2436 21 27 3322 32 33 32Total 309 275 295 282a. Do the data present sufficient evidence to indicatedifferences in location for at least two of the fourage groups? Test using the KruskalWallis H-testwith a .01. b. Find the approximate p-value for the test in part a.c. Since the F-test in Exercise 11.60 and the H-test inpart a are both tests to detect differences in locationof the four heart-rate populations, how do the testresults compare? Compare the p-values for the twotests and explain the implications of the comparison.
