Question

a survey asked 250 high school students, the students were asked how often they go to the movies and whether they prefer action movies or dramas. their responses are summarized in the following table.

(a) what percentage of the students go to the movies three times a month or more?
(b) what percentage of the students prefer action movies?

Explanation:

Step1: Calculate total number of students

Total students = \(78 + 31+162 + 38=309\)

Step2: Calculate number of students who go to movies three times a month or more

Number of students who go to movies three times a month or more = \(78+31 = 109\)
Percentage = \(\frac{109}{309}\times100\approx35.3\%\)

Step3: Calculate number of students who prefer action movies

Number of students who prefer action movies = \(78 + 31=109\)
Percentage = \(\frac{109}{309}\times100\approx35.3\%\)

Answer:

(a) Approximately \(35.3\%\)
(b) Approximately \(35.3\%\)
