Question

Ryan and Archie conduct a survey to see how many students would have a pet rat if their parents would let them. Ryan surveyed students and said they would. Archie thought that surveying more students would be more accurate. He surveyed students and of them said they would. Based on Ryan’s sample, estimate what percent of students would own a rat. Round to the nearest percent. Based on Archie’s sample, estimate what percent of students would own a rat. Round to the nearest percent.

Answer 1

Explanation:

We can use proportions to estimate the percentage of students who would own a pet rat.

Ryan surveyed students and said they would. This means that the proportion of students who said they would own a rat is:

$\frac{120}{200}$ = 0.6

To convert this to a percentage, we can multiply by 100:

0.6 × 100 = 60%

So based on Ryan's sample, we can estimate that 60% of students would own a pet rat if their parents would let them.

Archie surveyed 500 students and 200 of them said they would own a rat. This means that the proportion of students who said they would own a rat is:

$\frac{200}{500}$ = 0.4

To convert this to a percentage, we can multiply by 100:

0.4 × 100 = 40%

So based on Archie's sample, we can estimate that 40% of students would own a pet rat if their parents would let them.
