One hundred fifty-three of the 258 high school students surveyed at a local school say they went outside more during school hours as elementary school students than they do now as high school students. Calculate the margin of error (ME), rounded to the nearest tenth of a percent. Is it reasonable that the state education department claims the percentage for the entire state is 63%? Justify your answer.

Hint: , where  is the yes proportion in the sample and N is the sample size.

 

A. Yes, it is reasonable because the ME is 6.1% and the population proportion of 59% falls within the sample interval of 63.0% ± 6.1% 

B. No, it is not reasonable because the ME is 3.1% and the population proportion of 63% falls outside the sample interval of 59.3% ± 3.1%

C.Yes, it is reasonable because the ME is 6.1% and the population proportion of 63% falls within the sample interval of 59.3% ± 6.1% 

D. No, it is not reasonable because the ME is 6.1% and the population proportion of 63% falls outside the sample interval of 59.3% ± 6.1%
