Sagot :

Answer:

159.27cm

Step-by-step explanation:

To get the mean of a set of numbers, just divide the sum of the numbers with how many numbers is in the set.

In your case,

n = 15 (numbers given in a set)

s = (163 + 170 + 155 + 141 + 165 + 172 + 120 + 168 + 164 + 169 + 172 + 150 + 163 + 169 + 148)

s = 2389

Now divide s by n, 2389 / 15 = 159.27cm.
