A random number generator picks a number from 6 to 65 in a uniform manner. Round answers to 4 decimal places when possible.

  1. The mean of this distribution is   .
  2. The standard deviation is   .
  3. The probability that the number will be exactly 48 is
        P(x=48)=P(x=48)=   .
  4. The probability that the number will be between 17 and 22 is
        P(17<x<22)=P(17<x<22)=   .
  5. The probability that the number will be larger than 50 is
        P(x>50)=P(x>50)=   .
  6. P(x>24∣x<57)=P(x>24∣x<57)=   .
  7. Find the 21st percentile.  
  8. Find the minimum for the upper quarter.
