Dr. Loras Tyrell was curious to see if his students actually saved money by purchasing books from sources other than the college bookstore. He administered a survey to all his students asking how they obtained their book (Bookstore, Rented, ebook, or on the web – WebBooks) and how much they paid for the book. He obtained the information below.
If the values are normally distributed, we know that of the students who purchased the eBook, about 95.4% of those students paid approximately $----- to ----?
The New York Times reported that Apple has unveiled a new iPad marketed specifically to school districts for use by students (The New York Times website).
The 9.7-inch iPads will have faster processors and a cheaper price point in an effort to take market share away from Google Chromebooks in public school
districts. Suppose that the following data represent the percentages of students currently using Apple iPads for a sample of 18 U.S. public school districts.

- A cell phone service provider claims that only 1% of their calls get "dropped" (i.e., neither party hangs up, but the connection is lost). You work for the Consumer Protection Agency, and believe that the percent of dropped calls from this provider is higher than 1%. Your agency has been granted access to this company's detailed call records. It takes careful examination of each call transaction to determine if the call can be considered a "dropped call", so you are not able to easily calculate the actual percent of dropped calls directly from the entire database of millions of calls. So, you decide to take a random sample of 2500 calls, and each call is classified as "dropped" or "not dropped". Of the 2500 calls examined, 1.462% of them were classified as "dropped". Calculate the appropriate test statistic. Enter with 2 decimals (eg. 1.96).arrow_forwardYou're a data analyst for an insurance company. You want to make sure that your employer is not over-paying for car repairs. To investigate this, you bring 38 different cars to two different garages, Bubba's Hubcap Heaven and Repair, and Merle's Motor Shop. Some of the cars need lots of repairs. Some of the cars need very few. By taking each car to both shops, we can directly compare the two sets of prices. The dataset is in an Excel file named "Bubba_v_Merle_3899.xls", which you can find in the "Data" folder under Course Documents. Before running your analysis, be sure to look at the data file and verify that each car requires a different amount of repairs, and that prices in one shop are correlated with prices at the other shop. That is, they're in the same ballpark. The question is whether one tends to charge more, on average, than the other.

- Nationally, the proportion of red cars on the road is 0.12. A statistically-minded fan of the Philadelphia Phillies (whose team color is red) wonders if fans who park at Citizens Bank Park (the Phillies home field) are more likely to drive red cars. One day during a home game, he takes an SRS of 210 cars parked in the lot while a game is being played, and counts 35 red cars. (There are 21,000 parking spaces.) Is this convincing evidence that Phillies fans prefer red cars more than the general population? Provide statistical evidence to support your conclusion. Use the 4-step process.arrow_forwardAn insurance company offers four different deductible levels—none, low, medium, and high—for its homeowner's policyholders and three different levels—low, medium, and high—for its automobile policyholders.
