Page 366: 35, 37, 39, 41, 43, 45

**These are the same problems on the sheet I gave you today in class. (The sheet I gave you is just the problems from the booked typed up, so you don't have to carry your book maybe...)

Remember, all make up work--homework from when you were absent, missing quizzes, anything--is DUE BY WEDNESDAY. 

On Monday we'll get into some new stuff (and answer homework questions) from chapter 16--expected value and variance!

In case you aren't using your book (because I typed up the problems for you), here are the homework answers:

35.) a. No, the flight leaving on time and luggage making the connection are not independent, because the probability the luggage makes the connection is dependent upon whether the flight arrives on time (95% chance the luggage arrives if the flight is on time, 65% chance if it isn't on time).
b. 0.695

37.) 0.975

39.) a.) No, absenteeism is not independent of shift worked. It appears night shift workers are more likely to be absent (2% vs. 1%).
b. 0.014

41.) 0.571

43.) a. 0.2
b. 0.272
c. 0.353
d. 0.033

45.) 0.563
