Answer

Explanation:

Step1: Calculate total number of people surveyed

Total = 47 + 13+53 + 3=116

Step2: Calculate value of a (relative - frequency of males who enjoyed)

a=\frac{47}{116}\times100%\approx41%

Step3: Calculate value of b (relative - frequency of females who did not enjoy)

b = \frac{3}{116}\times100%\approx3%

Answer:

a = 41%, b = 3%
