Setting:

the city of valley grove is considering shortening the length of the school day. the school board hired mr. kent to do a survey to them decide what to do.

what i have to

a. mr. kent interviewed 54 students as they left the school. is this a random sample? explain.

b. mr. kent used this survey question: "should the lengthy school day, which now extends for 7.5 hours, be shortened to 6 hours? " is this question biased or fair? explain.

c. of the 54 responses he received, 51 were "yes." the rest were "no." what percent of the responses were "no"?

A. Mr. Kent interviewed the 54 students as they are going to leave the school, it is not considered to be a random sample. It is because a random sample is when a set is taken from a population. Mr. Kent interviewed the 54 who are going to leave, meaning, he didn't take a set out of that 54, he took all of them. So it is not a random sample.

b. The question that Mr. Kent asked is considered to be a leading question, so it does not seem biased.

c. If there are 54 respondents.
51 = yes, the rest is no.
= 54 - 51 = 3
= 3 is now divided to 54 = 3/54
= giving an answer of 0.0555
= 0.0555 x 100
= 5.6%
= The percent of responses that says 'no' is 5.6%

The answer simplified would be. -6300x
