I have all the answers for c I just need to make sure I am correct. For b I am a little lost. For a I have the answer but I know I am probably wrong.
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 help them decide what to do.
a. Mr. Kent interviewed 54 students as they left the school. Is this a random sample? Explain.no. Cause they are leaving they don't wanna be in school.
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”?
%5.6 said nope
Interviewing only students is not a random sample.
The question is definitely biased. His use of the adjective "lengthy" is prejudicial in this question.
c. is right.
