Question

As people exited a movie theater, they were informally surveyed about whether they enjoyed the movie or not.

Answer 1

Answer:

The answer is B. a = 41%, b = 3%

Answer 2

I'll just do a relative frequency for the whole table:

                   Enjoyed           Did not Enjoy             Total
Males             47                    13                           60
Females         53                      3                           56
Total             100                    16                         116 

                    Enjoyed                Did not Enjoy             Total
Males             47/116 = 0.41       13/116 = 0.11             60/116 = 0.52
Females         53/116 = 0.45         3/116 = 0.03             56/116 = 0.48
Total             100/116 =0.86        16/116 = 0.14           116/116 = 1.00

I'm not sure where a and b should be but based on the table: it can a = 41% ; b = 3% or a = 47% or b = 3%
