Question:

The resting pulse rates of 20-39 years old males in the United States was estimated as 71±0.4 (mean ± SE) BPM for non-Hispanic whites and 69±0.4 (mean ± SE) BPM for non-Hispanic blacks (Ostchega et al., 2001). Based on these data can we be 95% certain that among 20-39 year old males in the United States, non-Hispanic whites have higher resting pulse rates than non-Hispanic blacks? Defend your answer. PLEASE EXPLAIN. DO NOT JUST ANSWER A SENTENCE


Answers

In order to be 95% sure ; we have to find out the p-value for the hypothesis.

The null hypothesis is that "Among 20-39 year old males in Unites States ; non-Hispanic whites do not have higher resting pulse rates than non-Hispanic blacks."

The alternative hypothesis will be "Among 20-39 year old males in Unites States ; non-Hispanic whites have higher resting pulse rates than non-Hispanic blacks."

But for testing the hypothesis ; we need the value of 'n ;.i.e. the number of people (both non-Hispanic white and non-Hispanic black) from which the data has been collected.So it is not possible to be 95% certain.
