Answer
Explanation:
Step1: Calculate total number of males
Total number of males = 47 + 13 = 60.
Step2: Calculate total number of people surveyed
Total number of people surveyed = 47+13 + 53+3=116.
Step3: Calculate value of a
a is the relative - frequency of males who enjoyed the movie. a=$\frac{47}{116}\times100%\approx41%$.
Step4: Calculate value of b
b is the relative - frequency of females who did not enjoy the movie. b = $\frac{3}{116}\times100%\approx3%$.
Answer:
a = 41%, b = 3%
