Provide an appropriate response. Use the Standard Normal Table to find the probability. An airline knows from experience that the distribution of the number of suitcases that get lost each week on a certain route is approximately normal with muμequals=15.5 and sigmaσequals=3.6. What is the probability that during a given week the airline will lose less than 20 suitcases?

1. An airline knows from experience that the distribution of the number of suitcases that get lost each week on a certain route is approximately normal with μ = 15.5 and σ = 3.6. a) In one week, what is the probability that the airline will lose between 10 and 20 suitcases? b) In one year, how many weeks would you expect the airline to lose between 10 and 20 suitcases?
