Over the past week, I measured the resting heartrates of 24 women ages 30 -50 and got the following data measured in beats per minute:

61, 63, 64, 65, 65, 67, 71, 72, 73, 74, 75, 77, 79, 80, 81, 82, 83, 83, 84, 85, 86, 86, 89, 95

My claim is that the variance of heart rates for women ages 30 –50 is different than 12 beats per minute. Is there enough evidence to support my claim? Test at the 0.05 level of significance.

Solutions

Expert Solution

As we rejected the null hypothesis at 5% los, we conclude that the claim is true that the variance of heart rates for women ages 30 –50 is different than 12 beats per minute.

Suppose that over the past 30 years during any given week of the major-league season, an average of µ = 12 players are hit by wild pitches. Assume that the distribution is normal with a standard deviation of σ =3. For a sample of n = 4 weeks, in which the daily temperature was extremely hot, the weekly average of hit-by- pitch players was M = 15.5. Are players more likely to get hit by pitches during hot weeks? Use...

A certain group of symptom-free women between the ages of 40 and 50 are randomly selected to participate in mammography screening. The incidence rate of breast cancer among such women is 0.8%. The false negative rate for the mammogram is 10%. The false positive rate is 7%. If a the mammogram results for a particular woman are positive (indicating that she has breast cancer), what is the probability that she actually has breast cancer?
