13. random number generator picks a number from IE to 38 in a uniform manner. Round answers to 4 decimal places when possible. a. The mean of this distribution isI I b. The standard deviation is I I c. The probability that the number will be exactly 2'? is PD: = 2'9] = I I d. The probability that the number will be between '3 and 13 is F['9 c x 23} = I I i.P[x>11|X 3.11] = f_ pp; > 3.6 | K >1-9]=l:l g. Find the 89th percentile. I l h. Find the maximum for the lower quartile.
