Answer

Statement 1 is false.

Statement 2 and 3 are true.

The false statement includes

52% of the boys surveyed prefer mint chocolate chip ice cream.

The true statements include

- Approximately 20% of girls surveyed said they preferred mint chocolate chip ice cream.

- A total of 92 students prefer mint chocolate chip ice cream.

Step-by-step explanation

To answer this question and check which statement is true or false, we need to complete the table.

Mint Choc Chip | Cookies N Cream | Cookie Dough | Other | Total

Boys | 52 | 43 | 67 | 34 | 196

Girls | 40 | 59 | 61 | 41 | 201

Total | 92 | 102 | 128 | 75 | 397

Then, we can check the statements one at a time,

Statement 1

52% of the boys surveyed prefer mint chocolate chip ice cream.

Number of boys who prefer mint chocolate ice cream = 52

Total number of boys surveyed = 196

Percent of boys surveyed who prefer mint chocolate chip ice cream = (52/196) = 0.2653 = 26.53%

26.53% ≠ 52%

This statement is false.

Statement 2

Approximately 20% of girls surveyed said they preferred mint chocolate chip ice cream. *

Number of girls who prefer mint chocolate ice cream = 40

Total number of girls surveyed = 201

Percent of girls surveyed who prefer mint chocolate chip ice cream = (40/201) = 0.199 = 19.9% = 20% to the nearest percent

This statement is then true indeed.

Statement 3

A total of 92 students prefer mint chocolate chip ice cream.

Total number of students that prefer mint chocolate chip ice cream = 52 + 40 = 92

This statement is true.

Hope this Helps!!!
