Question

Male pulse rates and age. Using the pulse rates of males from Data Set "Body Data" after theynare partitoned into the three age brackets of 18-25, 26-40, and 41-80, we get the following SSPS display. Using a 0.05 significance level, test the claim that males from the three age brackets have the same mean pulse rate. What do you conclude?

SPSS

Sum of Sq df means sq f Sig

BG. 333.464 2 166,733 1,304 .275

WG. 19183.765 150 127,892

Total. 19517.229 152

Answer 1

Output for ANOVA is

	Sum of Sq	df	means sq	f	Sig
BG.	333.464	2	166.733	1,304	0.275
WG.	19183.77	150	127.892
Total.	19517.23	152

We have three groups here

1. age group 18-25
2. age group 26-40  
3. age group 41-80

Let be the pulse rate of ith group

So we want to test

vs

H1: at least one   is significantly different from others.

As we can see from the output the p-value for the test is  0.275 which is greater than the level of significance 0.05

we do not reject H0 at 5% level of significance and conclude that

males from the three age brackets have the same mean pulse rate.

Please give thumbs up if you like the answer.
