Round answers to 4 decimal places when possible Question 1 (0/5) Question 2 (1/1) Question 3 [1/1] Question 4 (1/1) a. The mean of this distribution is b. The standard deviation is c. The probability that the number will be exactly 17 is P(x - 17) - d. The probability that the number will be between 24 and 38 is P(24<x<38) e. The probability that the number will be larger than 32 is P(x > 32) = f. P(x > 16 x64) - 8. Find the 54th percentile h. Find the minimum for the lower quartile.
