Compute the mean and variance of the following probability distribution. (Round your answers to 2 decimal places.) X P(X) 7 0.10 11 0.35 15 0.20 19 0.35
Added by Gary D.
Step 1
The mean is calculated by multiplying each outcome by its probability and then summing these products. Mean = (7 * 0.10) + (11 * 0.35) + (15 * 0.20) + (19 * 0.35) = 0.7 + 3.85 + 3 + 6.65 = 14.2 Show more…
