Question

For a class project, you randomly ask fellow students whether they smoke. A summary of the response is given in the table below.

Male Female Smokes A 68 Does Not Smoke B 355

Unfortunately, the two entries for males were lost when your roommate spilled coffee on your work. However, before this happened, you determined that:

1. 18.3333333333333% of surveyed males smoke.

2. 59.1666666666667% of surveyed nonsmokers were female.

Based on this additional information, determine the missing table values A and B. (Your answers should be whole numbers.)

A =

B =

Explanation / Answer

from above   59.1666666666667% of surveyed nonsmokers were female.

therefore 355/(B+355) =0.5917

B =600-355=245

now 18.3333333333333% of surveyed males smoke.

therefore A/(A+245) =0.18333

A =55

therefore A =55

B =245
