A miniature golf course was recently added at the fairgrounds in a U.S. state. To see what sorts of people are visiting this new attraction, a survey was done at this year's state fair. It was found that, among a random sample of 79 couples at the fair with their children, 44 had visited the new miniature golf course, and among an independently chosen, random sample of 70 couples at the fair on a date (without children), 23 had visited the miniature golf course. Based on these samples, can we conclude, at the 0.01 level of significance, that the proportion p, of all couples attending the fair with their children who visited the miniature golf course is different from the proportion p₂ of all couples attending the fair on a date who visited the miniature golf course? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below.

Transcribed Image Text:A miniature golf course was recently added at the fairgrounds in a U.S. state. To see what sorts of people are visiting this new attraction, a survey was done at
this year's state fair. It was found that, among a random sample of 79 couples at the fair with their children, 44 had visited the new miniature golf course, and
among an independently chosen, random sample of 70 couples at the fair on a date (without children), 23 had visited the miniature golf course.
Based on these samples, can we conclude, at the 0.01 level of significance, that the proportion p, of all couples attending the fair with their children who visited
the miniature golf course is different from the proportion p₂ of all couples attending the fair on a date who visited the miniature golf course?
Perform a two-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. (If necessary, consult a list of
formulas.)
(a) State the null hypothesis Ho and the alternative hypothesis H₁.
