In May $2008$, CNN reported that sports utility vehicles (SUVs) are plunging toward the "endangered" list. Due to the uncertainty of oil prices and environmental concerns, consumers are replacing gas-guzzling vehicles with fuel-efficient smaller cars. As a result, there has been a big drop in the demand for new as well as used SUVs. A sales manager of a used car dealership for SUVs believes that it takes more than $90$ days, on average, to sell an SUV. In order to test his claim, he samples $40$ recently sold SUVs and finds that it took an average of 95 days to sell an SUV. He believes that the population standard deviation is fairly stable at $20$ days.

Sports announcers frequently get excited when basketball players make several free throw shots in a row. They say things like "He's on a hot streak tonight!" or "He's really in the zone-what an amazing performance!" Are these "hot" streaks really special, or are they just a natural run to be expected by probability? Assume a basketball player has a 50% free throw average, and a typical game has 20 free throw attempts. Use your calculator to set up a simulation for 20 free throws. a. Run the simulation 25 times, and each time record the length of the longest streak. b. How long would a streak have to be before you considered it unusual?

The local sports shop is having a sale on bats and balls, with a limit of one bat and one ball per customer. The owner of the store, Mr. Blake, thinks that a customer who purchases a bat is more likely to purchase a ball than a customer who does not purchase a bat. He analyzes the sales from the last week and finds that a total of 240 customers came into the store. He counts 180 customers who purchased bats and 96 customers who purchased balls. Mr. Blake then counts the number of sales that include both a bat and a ball and finds that 72 customers purchased both. Is there an association between the purchase of bats and balls? Explain and show your reasoning using the relationships that you have learned in this lesson.

A local television station surveys some of its viewers to determine the primary reason they watch the station . The two-way frequency table gives the survey data. Determine whether a viewer is a man and a viewer primarily watches the station for entertainment are independent events.

$$\begin{array}{|l|c|c|c|} \hline {} & \begin{array}{c} \text { Primarily Watches for } \\ \text { Imformation (News, } \\ \text { Weather, Sports) } \end{array} & \begin{array}{c} \text { Primarily Watches } \\ \text { for Entertainment } \\ \text { (Comedies, Dramas) } \end{array} & \text { Total } \\ \hline \text { Men } & 28 & 12 & 40 \\ \hline \text { Women } & 35 & 15 & 50 \\ \hline \text { Total } & 63 & 27 & 90 \\ \hline \end{array}$$

Gambling is an issue of great concern to those involved in college athletics. Because of this concern, the National Collegiate Athletic Association (NCAA) surveyed randomly selected student athletes concerning their gambling-related behaviors. Of the 5594 Division I male athletes in the survey, 3547 reported participation in some gambling behavior. This includes playing cards, betting on games of skill, buying lottery tickets, betting on sports, and similar activities. A report of this study cited a 1% margin of error. The study was designed to protect the anonymity of the student athletes who responded. As a result, it was not possible to calculate the number of students who were asked to respond but did not. How does this fact affect the way that you interpret the results?

A newspaper publisher trying to pinpoint his market’s characteristics wondered whether the way people read a newspaper is related to the reader’s educational level. A survey asked adult readers which section of the paper they read first and asked to report their highest educational level. These data were recorded (column 1 = First section read where 1 = Front page, 2 = Sports, 3 = Editorial, and 4 = Other) and column 2 = Educational level where 1 = Did not complete high school, 2 =High school graduate, 3 = University or college graduate, and 4 = Postgraduate degree). What do these data tell the publisher about how educational level affects the way adults read the newspaper?

On a separate sheet of paper, draw a scatter plot for each data set and find its line of best fit. Explain what each graph tells you.
