Module 10 Task A research study was conducted to examine the differences between older and younger adults on systolic blood pressure. Ten older adults (Over 70) and ten younger adults (between 20 and 30) had their blood pressures measured. The data are presented below: Older Adults Younger Adults 144 117 139 108 119 131 128 128 137 126 114 115 149 112 122 119 134 129 127 124 1. What is the null hypothesis in this study? 2. What is the alternative hypothesis? 3. What is the mean BP for older adults and for younger adults? 4. Calculate the appropriate t-score and p-value. 5. Is age associated with blood pressure? Is it statistically significant? A researcher hypothesizes exercise is associated with food intake in college students. Caloric intake was recorded for a group of student participants on a day with exercise and on a day without exercise. The data are presented below: Exercise No Exercise 2485 2185 3758 1956 2964 2745 3458 2946 2617 2785 3952 3485 2845 2647 1954 2125 3481 3152 2643 2764 6. What is the null hypothesis in this study? 7. What is the alternative hypothesis? 8. What is the mean caloric for students when they exercise and when they don't exercise? 9. Calculate the appropriate t-score and p-value. 10. Is exercise associated with food intake? Is it statistically significant
