Does systolic blood pressure increase with age? If so, by how much? A sample of 27 individuals was randomly selected from a population with ages ranging from 20 to 70 years. The response variable is measured as the average systolic blood pressure at a fixed time during the day over a 1-week period. age (x) : 34 26 51 58 34 48 31 57 46 53 20 58 48 34 bp (y): 116 112 153 158 122 125 119 152 148 155 128 148 148 138 age (x) : 67 23 47 42 61 38 57 66 42 53 38 48 58 bp (y): 172 110 138 138 163 128 161 177 130 145 125 158 135 Hint: Ex = 1199 Ey = 3770 I(x - ) = 3874.519 I(x - X)(y - ) - 5478.074 D(y - 3) - 8726.296 Scatterplot 170 150 SystolicBP 130 110 30 40 50 60 Age The average blood pressure of individuals in this population that are 64 years old is closest to: O A: 172 O B: 170 O C: 169 O D: 173 E: 167
