Calculate P(9.5 s x S 12). b. Determine P(x > 11). c. Compute the mean, u, and the standard deviation, o, of this random variable. of 8 d. Determine the probability that x is in the interval (u +36). a. P(9.5 SX S 12) = (Simplify your answer.) al s b. P(x > 11) = N / - (Simplify your answer.) C. H = 11 (Simplify your answer.) o= 1.155 (Round to three decimal places as needed.) d. P(u - 30 SXSu+ 30) = (Round to three decimal places as needed.)
