Medicare would like to test the hypothesis that the average monthly rate for one-bedroom assisted-living facility is equal to $3,300. A random sample of 12 assisted-living facilities had an average rate of $3,690 per month. The standard deviation for this sample was $530. Medicare would like to set α = 0.05. The test statistic for this hypothesis test would be ________.

Sony would like to test the hypothesis that the average age of a PlayStation user is different from the average age of an Xbox user. A random sample of 36 PlayStation users had an average age of 34.2 years while a random sample of 30 Xbox users had an average age of 32.7 years. Assume that the population standard deviation for the age of PlayStation and Xbox users is 3.9 and 4.0 years, respectively. Sony would like to set α = 0.10. If Population 1 is defined as PlayStation users and Population 2 is defined as Xbox users, the test statistic for this hypothesis test would be ________.

Expedia would like to test the hypothesis that the average roundtrip airfare between Philadelphia and Paris is higher for a flight originating in Philadelphia when compared to a flight originating in Paris. The following data summarizes the sample statistics for roundtrip flights originating in both cities. Assume that the population variances are equal.Originating City PhiladelphiaParisSample mean$1,240$1,060Sample size1519Sample standard deviation$270$240If Population 1 is defined as flights originating in Philadelphia and Population 2 is defined as flights originating in Paris, and using α = 0.05, the correct test statistic for this hypothesis is

Many hotel chains that offer free Wi-Fi service to their customers have experienced increasing demand for Internet bandwidth and increasing costs. Marriott International would like to test the hypothesis that the proportion of customers that are carrying two Wi-Fi devices exceeds 0.60. A random sample of 120 Marriott customers found that 78 have two Wi-Fi devices. Marriott International would like to set α = 0.01. The correct hypothesis statement for this hypothesis test would be ___________________________.

CoStar would like to test if the vacancy rate for “warehouse” stores is at least 8%. The correct hypothesis statement to test for this vacancy rate would be ______________________.

Are Japanese managers more motivated than American managers? A randomly selected group of each were administered the Sarnoff Survey of Attitudes Toward Life (SSATL), which measures motivation for upward mobility. The SSATL scores are summarized below.  Using the above information, suppose that the test statistic is 2.45. Find the p-value if we assume that the alternative hypothesis was a two-tailed test (H1 : μA – μJ ≠ 0).
