Answer:
7
Step-by-step explanation:
σ = 4 ; μ =?
8.52 to the left of X
.
P(X < 8.52) = 64.8%
P(X < 8.52) = 0.648
Using the Z relation :
(x - μ) / σ
P(Z < (8.52 - μ) / 4)) = 0.648
The Z value of 0.648 of the lower tail is equal to 0.38 (Z probability calculator)
Z = 8.52 - μ / 4
0.38 = 8.52 - μ / 4
0.38 * 4 = 8.52 - μ
1.52 = 8.52 - μ
μ = 8.52 - 1.52
μ = 7
Start by taking the total number of golf balls, 360, and dividing it by how many golf balls come in each pack, to find the number of packs.
360 ÷ 24 = 15
So there are 15 packs, each with 3 yellow golf balls.
15 · 3 = 45
Meaning 45 of the golf balls would be yellow
