n a survey of 500 males ages 20 to 24, 13.8% were neither in school nor working. In a survey of 500 females ages 20 to 24, 17.8% were neither in school nor working. At  α = 0 . 05 , can you support the claim that the proportion of males ages 20 to 24 who were neither in school nor working is less than the proportion of females ages 20 to 24 who were neither in school nor working? Based on the conclusion from Problem 6 (A), what type error might you have made: Type 1 or Type 2? [BLANK-1]

A pet association claims that the mean annual costs of routine veterinarian visits for dogs and cats are the same. The results for samples of the two types of pets are shown below. It is reasonable to assume that the poulation variances are the same.  Picture46(1).png  At α = 0 . 05 , can you reject the pet association’s claim? What is the correct critical value for this hypothesis test? Capture72(3).PNG 

A sports statistician claims that the mean winning times for Boston Marathon’s women’s open division champions is at least 2.68 hours. The mean winning time of a sample of 30 randomly selected Boston Marathon women’s open division champions is 2.60 hours. Assume the population standard deviation is 0.32 hour. At α = 0 . 05 , does this statistician have support of his claim? The calculated standardized test statistic for this situation is  z = – 1 . 37 with a  p -value of  p = 0 . 0855 . What is the correct conclusion for this result?
