Three different shops are used to repair electric motors. One hundred motors are sent to each shop. When a motor is returned, it is put in use and then repair is classified as complete, requiring and adjustment, or incomplete repair. Based on data in Table 4, use 0.05 level of significance to test whether there is homogeneity among the shops’ repair distribution.

At a TV assembling facility, the Quality Assurance (QA) department tested a random selection of 500 TV's assembled in March. The tested TV's had an average retail price of $475, 2.4% had some type of defect, and 7 did not power up at all. The plant manager compared that to the total 6753 of TV's that were assembled during the month of March. They had an average retail price of $395 , 3.2% had been reported defective by customers, and did not power up at all. For the QA department's tests, identify the population and the sample. Choose whether each number described below is a parameter or a statistic for the QA department's tests. Number Parameter Statistic The 7 TV's of the random selection of 500 TV's that did not power up at all The 2.4% of the random selection of 500 TV's found to be defective The average retail price of $395 of all the TV's assembled during the month of March

The table cross-classifies 68,694 passengers in cars and light trucks involved in accidents in the state of Maine by whether or not they were wearing a seat belt and by whether or not they were injured or killed. The study is using seatbelt wearing to predict injury/death. Injured or Killed? Wore Seatbelt?

What are the odds that a passenger was injured or killed if he/she wore a seatbelt (Row 2 odds)? Interpret both results. Describe the strength of the association between seatbelt use and injury/death using the odds ratio. Calculate the odds ratio and interpret the result?

Based on a survey of 12,344 U.S. college students and 6,729 Canadian college students, Kuo, Adlaf, Lee, Gliksman, Demers, and Wechsler (2002) report that alcohol use is more common among Canadian than U.S. students, but heavy drinking (five or more drinks in a row for males, four or more for females) is significantly higher among U.S. students than Canadian students. Is this an example of a survey research design?
