Ryan and Archie conduct a survey to see how many students would have a pet rat if their parents would let them. Ryan surveyed 15 students and 2 said they would. Archie thought surveying more students would be more accurate. he surveyed 150 students and 16 of them said they would.
Based of Ryan's sample, estimate what percent of students would own a rat. Round to the nearest percent.
Based of Archie's sample, estimate what percent of students would own a rat. Round to the nearest percent.
Based on Ryan's sample of 15 students, 2 of them said they would have a pet rat. So, the estimated percentage of students who would have a pet rat is:
(2/15) x 100 = 13%
Based on Archie's sample of 150 students, 16 of them said they would have a pet rat. So, the estimated percentage of students who would have a pet rat is:
(16/150) x 100 = 11%
Therefore, based on the estimates from the two samples, approximately 13% of students would have a pet rat according to Ryan's sample and approximately 11% of students would have a pet rat according to Archie's sample.
