A physician wants to develop criteria for determining whether a patient?s pulse rate is atypical, and she wants to determine whether there are significant differences between males and females. Use the sample pulse rates in Data Set 1 from Appendix B.

a. Construct a 95% confidence interval estimate of the mean pulse rate for males.

b. Construct a 95% confidence interval estimate of the mean pulse rate for females.

c. Compare the preceding results. Can we conclude that the population means for males and females are different? Why or why not?

Data Set 1: Health Exam Results AGE is in years, HT is height (inches), WT is weight (pounds), WAIST is circumference (cm), Pulse is pulse rate (beats per minute), SYS is sys- tolic blood pressure (mm Hg), DIAS is diastolic blood pressure (mm Hg), CHOL is cholesterol (mg), BMI is body mass index, Leg is upper leg length (cm), Elbow is elbow breadth (cm), Wrist is wrist breadth (cm), and Arm is arm circumfer- ence (cm). Data are from the U.S. Department of Health and Human Services, National Center for Health Statistics, Third National Health and Nutrition Examination Survey. 58 70.8 169.1 90.6 68 125 22 66.2 144.2 78.1 64 107 71.7 179.3 96.5 88 126 32 31 68.7 175.8 87.7 28 67.6 152.6 87.1 Male Age HT WT Waist Pulse SYS DIAS CHOL BMI 46 69.2 166.8 41 66.5 135.0 72 110 92.4 78.8 72 107 60 56 67.2 201.5 103.3 88 126 20 68.3 175.2 89.1 76 60 64 110 113 96 72 137 54 65.6 139.0 82.5 17 63.0 156.3 86.7 73 68.3 186.6 103.3 52 73.1 191.1 91.8 25 67.6 151.3 75.6 29 68.0 209.4 105.5 17 71.0 237.1 108.7 41 61.3 176.7 104.0 52 76.2 220.6 103.0 76 91.3 84 32 66.3 166.1 20 69.7 137.4 75.2 88 20 65.4 164.2 87.7 72 29 70.0 162.4 56 77.0 85.0 68 18 62.9 151.8 26 68.5 144.1 79.6 64 110 110 33 68.3 204.6 103.8 60 55 69.4 193.8 103.0 68 125 53 69.2 172.9 97.1 60 124 28 68.0 161.9 86.9 60 28 71.9 174.8 88.0 37 66.1 169.8 91.5 40 72.4 213.3 102.9 131 33 73.0 198.0 93.1 84 132 26 68.0 173.3 98.9 88 116 53 68.7 214.5 107.5 56 125 36 70.3 137.1 112 34 63.7 119.5 42 71.1 189.1 18 65.6 164.7 81.6 64 75.7 56 125 95.0 56 120 91.1 60 44 68.3 170.1 94.9 64 115 20 66.3 151.0 79.9 72 115 110 109 153 56 112 64 119 60 113 64 125 84 131 121 132 112 121 116 95 56 109 84 112 72 127 784686651728576578275 80 584 654 58 70 68279 894792447736875 65 83 75 81 STATDISK: Data set name for males is Mhealth.
