A research group surveyed
200

(a) What percentage of the students prefer action movies?
%
(b) What percentage of the students go to the movies twice a month or less?
%
(a) The total number of students who prefer action movies is 62+22=84. Out of the total number of students surveyed (200), the percentage who prefer action movies is (84/200) x 100% = 42%.
(b) The total number of students who go to the movies twice a month or less is 62+86=148. Out of the total number of students surveyed (200), the percentage of students who go to the movies twice a month or less is (148/200) x 100% = 74%.
To calculate the percentages, first, we need to find the total number of students in each category.
The total number of students who prefer action movies is 62 + 22 = 84.
The total number of students who go to the movies twice a month or less is 62 + 86 = 148.
Now, we can calculate the percentages.
(a) What percentage of the students prefer action movies?
The percentage of students who prefer action movies is (84/200) * 100 = 42%.
Therefore, 42% of the students prefer action movies.
(b) What percentage of the students go to the movies twice a month or less?
The percentage of students who go to the movies twice a month or less is (148/200) * 100 = 74%.
Therefore, 74% of the students go to the movies twice a month or less.
