For the given data, find ∑x, n, and x̅: x1 = 16, x2 = 21, x3 = 20, x4 = 17, x5 = 18, x6 = 17, x7 = 17, x8 = 11
Solution :
n = 8
= 16 + 21 + 20 + 17 + 18 + 17 + 17 + 11 = 137
= = 137 / 8 = 17.125
SOLUTION
∑x = 16+21+20+17+18+17+17+11 = 137 (ANSWER)
n = 8 (ANSWER)
x bar = ∑x / n = 137/8 = 17.125 (ANSWER)
