as people exited a movie theater, they were informally surveyed about whether they enjoyed the movie or not. males enjoyed: 47 did not enjoy: 13 females enjoyed: 53 did not enjoy: 3 survey on movie what are the values of a and b in the relative - frequency table for the survey results? round answers to the nearest percent. a = 40%, b = 4% a = 41%, b = 3% a = 47%, b = 3% a = 41%, b = 19%
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%
