(1 point)13
15
20
40

19. What percentage of the children chose peanut butter? (1 point)
25%
30%

Omg this was from 2013?!?! LORD

To find the answer to question 18, we need to add up the number of adults surveyed for each type of cookie.

For the Chocolate Chip cookie, there were 5 adults surveyed.
For the Peanut Butter cookie, there were 8 adults surveyed.
For the Oatmeal cookie, there were 7 adults surveyed.

Adding these numbers together, we have 5 + 8 + 7 = 20.

Therefore, the correct answer is 20 adults surveyed.

To find the answer to question 19, we need to calculate the percentage of children who chose peanut butter.

To do this, we need to find the total number of children surveyed and the number of children who chose peanut butter.

From the two-way frequency table, we can see that 10 children chose the Chocolate Chip cookie, 6 children chose the Peanut Butter cookie, and 4 children chose the Oatmeal cookie.

Adding these numbers together, we have 10 + 6 + 4 = 20 children surveyed.

Of these 20 children, 6 chose the Peanut Butter cookie.

To calculate the percentage, we can divide the number of children who chose Peanut Butter by the total number of children surveyed and then multiply by 100.

Therefore, (6/20) x 100 = 30%.

So, the correct answer is 30% of the children chose peanut butter.

To answer question 18, we need to find the total number of adults surveyed.

From the two-way frequency table, we can see that the number of adults who chose Chocolate Chip, Peanut Butter, and Oatmeal cookies are 5, 8, and 7, respectively.

So, the total number of adults surveyed would be the sum of these numbers:

Total number of adults = 5 + 8 + 7 = 20

Therefore, the correct answer to question 18 is option C) 20.

To answer question 19, we need to find the percentage of children who chose peanut butter cookies.

From the two-way frequency table, we can see that the number of children who chose Peanut Butter cookies is 6.

To find the percentage, we can use the formula:

Percentage = (Number of children choosing Peanut Butter / Total number of children) * 100

So, the percentage of children who chose peanut butter cookies is:

Percentage = (6 / (10 + 6 + 4)) * 100 = (6 / 20) * 100 = 30%

Therefore, the correct answer to question 19 is option B) 30%.
