Hypertension is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. In elderly patients with hypertension, a high systolic pressure can cause a fainting episode, so X transporting them to an emergency clinic is imperative. Let be the systolic blood pressure of elderly patients with hypertension on arrival at the emergency clinic after a fainting episode. A random sample of such patients was considered. The measurements of each patient, in mm Hg, are given below. At the 5% level of significance, can we conclude from the data in this sample that the mean systolic blood pressure of all elderly hypertensive patients transported to an emergency clinic after a fainting episode is smaller than 175 mm Hg? patient 1 2 3 4 5 6 7 8 9 10 11 12 13 14 X 166 178 153 157 178 158 153 169 182 155 151 195 202 169 patient 16 17 18 19 20 21 22 23 24 25 26 27 28 29 X 173 161 155 154 178 200 168 196 180 191 167 170 161 191 patient 31 32 33 34 35 36 37 38 39 40 41 42 43 44 X 167 163 157 201 204 159 154 192 162 182 165 190 154 150 patient 46 47 48 49 50 51 52 53 54 55 56 57 58 59 X 182 196 169 158 180 199 182 178 161 170 168 158 159 169
