Solution :
From given probability distribution,
Mean = = X * P(X) =
= 3 * 0.14 + 6 * 0.25 + 9 * 0.36 + 12 * 0.15 + 15 * 0.10
= 8.46
Mean = = 8.46

A golf ball manufacturer desires to compare the distance traveled by golf balls using four unique designs. Fifteen balls were manufactured and each was brought to the local golf course for testing by the local pro. The order of the golf balls hit by the professional was randomized so the pro did not know which ball was being hit. All 60 balls were hit over a short time period to reduce any potential environmental effects. A B C D 1...
1. Find the mean and Standard Deviation for the following probability distribution. Number of girls in 4 births: 0 , 1, 2 , 3, 4 Probability: 0.0625 , 0.25 , 0.375 , 0.25 , 0.0625 2. Mendel conducted experiments using pea plants. Assume that a pea has a 75% chance of having green pods. If Mendel collected 600 pea plants, how many pea plants would he expect to have green pods? 3. What is the Standard deviation for the previous...
