A random sample of 184 students at South High School were surveyed on whether they would prefer going to a movie or a concert. The results are shown in the relative frequency table. A 4-column table with 4 rows. The first column has no label with entries 10th, 11th, 12th, total. The second column is labeled movie with entries 0.18, 0.16, 0.24, 0.58. The third column is labeled concert with entries 0.15, 0.18, 0.09, 0.42. The fourth column is labeled total with entries 0.33, 0.34, 0.33, 1.00. Which statements are correct? Check all that apply. The marginal relative frequency for 10th graders is 0.18. 42% of the students prefer a concert over a movie. A greater ratio of 11th graders prefer a concert to a movie. More 12th graders were surveyed than any other grade level. The difference in the percent of students who prefer a movie over a concert is16%.

concert     .15     .18     .09   .42

total           .33     .34    .33    1

The marginal relative frequency for 10th graders is 0.18.   This is an incomplete statement

The marginal frequency is a number not a percent

The difference in the percent of students who prefer a movie over a concert is16%.  True

B. 42% of the students prefer a concert over a movie

C. A greater ratio of 11th graders prefer a concert to a movie

E. The difference in the percent of students who prefer a movie over a concert is 16%

Step-by-step explanation:

No. movie concert total

10th - 0.18 - 0.15 - 0.33

11th - 0.16 - 0.18 - 0.34

12th - 0.24 - 0.09 - 0.33

Total - 0.58 - 0.42 - 1.00

0.42 is 42%

(0.58 -0.42) × 100 = 16%

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
