question 10 of 10 ms. stewart teaches three science classes. her students are freshmen and sophomores. her student data are shown in the relative frequency table. which statement is false? a. 35% of her students are in chemistry. b. 35% of her students are in biology. c. 20% of her students are in physical science. d. 55% of her students are sophomores.

Answer

Explanation:

Step1: Analyze option A

Check chemistry total relative - frequency. From the table, the total relative - frequency for chemistry is 0.35, which means 35% of students are in chemistry. So option A is true.

Step2: Analyze option B

Check biology total relative - frequency. From the table, the total relative - frequency for biology is 0.35, which means 35% of students are in biology. So option B is true.

Step3: Analyze option C

Check physical science total relative - frequency. From the table, the total relative - frequency for physical science is 0.3, which means 30% of students are in physical science, not 20%. So option C is false.

Step4: Analyze option D

Check sophomores total relative - frequency. From the table, the total relative - frequency for sophomores is 0.55, which means 55% of students are sophomores. So option D is true.

Answer:

C. 20% of her students are in physical science.
