Q1) Find the value of both the sample mean and test statistics

Extracted text: Exercise 1 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 transporting them to an emergency clinic is imperative. Let x 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 this sample that the mean systolic blood pressure of all elderly hypertensive patients transported to an emergency clinic after a fainting episode is different from 164 mm Hg? patient x patient x patient x 1 152 19 154 37 141 146 20 158 38 147 3 145 21 152 39 173 4 159 22 142 40 161 160 23 181 41 161 6 173 24 186 42 145 7 160 25 159 43 169 8 153 26 145 44 149 146 27 169 45 152 10 160 28 140 46 154 11 183 29 145 47 160 12 160 30 169 48 182 13 146 31 182 49 173 14 148 32 173 50 164 15 144 33 170 51 150 16 160 34 185 52 179 17 171 35 150 53 157 18 155 36 156 54 186
