A random number generator picks a number from 20 to 43 in a uniform manner. Round answers to 4 decimal places when possible. a. The mean of this distribution is ? b.The standard deviation is ? c. The probability that the number will be exactly 41 is P(x = 41) =  d. The probability that the number will be between 23 and 41 is P(23 < x < 41) =  e. The probability that the number will be larger than 32 is P(x > 32) =  f.P(x > 24 | x < 37) =  g.Find the 53rd percentile.  h. Find the maximum for the lower quartile.
