Step 1
Expected value (E(X)) = 5 * 0.40 + 15 * 0.60 Expected value (E(X)) = 2 + 9 Expected value (E(X)) = 11 Show more…

3. Assume that X is normally distributed with a mean of 100 and a standard deviation of 15. Determine the following: a. P(X < 65) b. P(X > 101) c. P(95 < X < 105) d. P(50 < X < 75) 4. Assume that X is normally distributed with a mean of 100 and a standard deviation of 15. Find x for the following: a. P(X > x) = 0.6 b. P(X > x) = 0.99 c. P(x < X) = 0.1
