To find the mean height for question 8.2.1: Step 1: Recall the formula for the mean. The mean is calculated by summing all the values and dividing by the total number of values. Mean = heightsnumber of learners Step 2: Sum the heights of the 12 learners. The heights are 132, 132, 141, 142, 155, 156, 161, 162, 163, 169, 170, 172 cm. heights = 132 + 132 + 141 + 142 + 155 + 156 + 161 + 162 + 163 + 169 + 170 + 172 = 1855 cm Step 3: Calculate the mean height. There are 12 learners. Mean = (1855)/(12) ≈ 154.5833 cm Rounding to two decimal places, the mean height is 154.58 cm. The mean of the height of the 12 learners is 154.58 cm.
