Question:

  1. Using the appropriate statistical test, determine if there is a statistically significant difference in the average AGE between the three groups of subjects – those with low, normal, or high blood pressure

There are 959 data points. Here are a couple as an example. I just need to know what test to use.

ID Age BP * 0 = hypotensive, 1 = normal, 2 = hypertensive

1 66 0
2 60 1
3 71 2
4 54 1
5 54 0
6 62 2
7 54 1
8 51 2
9 51 0
10 65 1
11 59 2
12 65 1
13 70 0
14 72 2

Null hypothesis: The average AGE between the three groups of subjects are the same.

Alternative hypothesis: At least one subject has a different average Age.

One-way ANOVA:

Source DF SS MS F P
Blood pressure 2 32.0 16.0 0.26 0.776
Error 11 680.0 61.8
Total 13 712.0

S = 7.862 R-Sq = 4.50% R-Sq(adj) = 0.00%

Conclusion: The estimated p-value is 0.776 and more than 0.05 significance level. Hence, retain the null hypothesis and conclude that the average AGE between the three groups of subjects is the same at the 0.05 significance level.
