Claim: The standard deviation of pulse rates of adult males is less than 12 bpm. For a random sample of 144 adult males, the pulse rates have a standard deviation of 10.8 bpm. Find the value of the test statistic. The value of the test statistic is ???
Pulse Rates of Males Refer to Data Set 1 “Body Data” in Appendix B and use the pulse rates of males. a. Find the mean and standard deviation, and verify that the pulse rates have a distribution that is roughly normal. b. Treating the unrounded values of the mean and standard deviation as parameters, and assuming that male pulse rates are normally distributed, find the pulse rate separating the lowest 2.5% and the pulse rate separating the highest 2.5%. These values could be helpful when physicians try to determine whether pulse rates are significantly low or significantly high.

Question Help X6.2.21 A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 2.5 in. A branch of the military requires women's heights to be between 58 in and 80 in. a Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? b.

Page 2 of 21 8. Selling Cars: You sell a brand of automobile tire that has a life expectancy that is normally distributed with a mean life of 30,000 miles and a standard deviation of 2500 miles. You want to give a guarantee for free replacement tires if the tires wear out too soon, but you can only afford to give free replacements on approximately 5% of the tires you sell. How should you word your free replacement guarantee? Draw, shade and label a normal curve to illustrate your results.
