Question Description

  •  In the year 2000, the state of Indiana began a $40-million renovation of its state fairgrounds, which included the building of a miniature golf course and a state-of-the-art livestock building. Now, Indiana officials are interested in learning what sorts of people are visiting the new attractions. In a survey done at this year's state fair, it was found that, among a random sample of 76 couples at the fair with their children, 27 had visited the new miniature golf course, and among an independently chosen, random sample of 72 couples at the fair on a date (without children), 32 had visited the miniature golf course. Based on these samples, can we conclude, at the 0.1 level of significance, that the proportion p(with a little one) of all couples attending the fair with their children who visited the miniature golf course is different from the proportion p(two) of all couples attending the fair on a date who visited the miniature golf course?

    Perform a two-tailed test. Then fill in the table below.

    Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)

    a)null hypothesis
  •  b)alternative hypothesis
  •  c)type of test
  •  d)value of the test statistic
  •  e)the p-value
