16.Suppose a news article reported that "two research teams found that the risk of a heart attack during heavy physical exertion

wasthreetosixtimes greater than during less strenuous activity or inactivity." It was implicit, but not stated, that these results were for those who do not exercise regularly.

1.There is a confidence interval reported in this statement. What is this confidence interval?

2.Explain what characteristic of the population it is measuring.

a)It is measuring the risk of having a heart attack during physical exertion.

b)It is measuring the relative risk of having a heart attack during physical exertion for a population that exercises regularly versus irregularly or not at all.

c)It is measuring the relative risk of having a heart attack during heavy versus minimal physical exertion.

d)It is measuring the odds of having a heart attack during physical exertion.

e)It is comparing the population means of having a heart attack during heavy versus minimal physical exertions.

f)It is comparing the population means of heart attacks during physical exertion for a population that exercises regularly versus irregularly or not at all.
