Q1      An employment agency has found that the mean time required for applicants to finish an aptitude test is normally distributed with a mean of 24.5 minutes and a standard deviation of 4.5 minutes.

  1. What is the probability that an applicant will finish the aptitude test in 22 minutes or less?
  2. What is the probability that an applicant will finish the test in between 28 to 35 minutes?
  3. The director for the agency would like to set a time limit for the aptitude test so that only 2% of the applicants will be unable to finish the test. What would be the time limit for this aptitude test?
