Question

the conditional relative frequency table was generated using data that compares the favorite subjects of male and female students at a high school. the survey was given to 120 male students and 180 female students. how many students in the survey said that math was their favorite subject? 42 81 120 123

Explanation:

Step1: Calculate number of male students who like math

Multiply number of male students by male - math relative - frequency. $120\times0.35 = 42$.

Step2: Calculate number of female students who like math

Multiply number of female students by female - math relative - frequency. $180\times0.45=81$.

Step3: Calculate total number of students who like math

Add results from Step 1 and Step 2. $42 + 81=123$.

Answer:

123
