Three different brands of automobile batteries, each one having a 42-month warranty, were included in a study of battery lifetime. A random sample of batteries of each brand was selected and lifetime (in months) was determined, resulting in the following data. Brand 1 45 39 52 47 45 41 43 Brand 2 39 44 50 53 48 47 40 Brand 3 50 47 43 48 56 44 48 State and test the appropriate hypotheses using a significance level of 0.05. State the appropriate null and alternative hypotheses. (Let ?1, ?2, and ?3 be the true mean lifetimes for the three brands.)

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1403 referee calls, with the result that 417 of the calls were overturned. Women challenged 741 refereecalls, and 215 of the calls were overturned. Use a 0.01 significance level to test the claim that men and women have equal success in challenging calls.

In his book Outliers, author Malcolm Gladwell argues that more baseball players have birthdates in the months immediately following July 31, because that was the cutoff date for nonschool baseball leagues. Here is a sample of frequency counts of months of birthdates of American-born major league baseball players starting with January; 375, 333, 360, 346, 335, 315, 317, 509, 419, 424, 399, 374. Using a 0.10 significance level, is there sufficient evidence to warrant rejection of the claim that American-born major league baseball players are born in different months with the same frequency? Do the sample values appear to support Gladwell's claim?
Four brands of lightbulbs are being considered for use in the final assembly area of the Ford F-150 truck plant in Dearborn, Michigan. The director of purchasing asked for samples of 200 from each manufacturer. The numbers of acceptable and unacceptable bulbs from each manufacturer are shown below. At the 0.10 significance level, is there a difference in the quality of the bulbs?
The City of South Lake Tahoe, CA, has an Asian population of 1,419 people, out of a total population of 23,609. Suppose that a survey of 1,419 self-reported Asians in the Manhattan, NY, area yielded the data in the table below. Conduct a goodness-of-fit test to determine if the the self-reported sub-groups of Asians in the Manhattan area fit that of the Lake Tahoe area. (Use a significance level of 0.05.) Race Lake Tahoe Frequency Manhattan Frequency Asian Indian 131 174 Chinese 118 557 Filipino 1,045 518 Japanese 80 54 Korean 12 29 Vietnamese 9 21 Other 24 66 State the distribution to use for the test.

The research department at the home office of New Hampshire Insurance conducts on-going research on the causes of automobile accidents, the characteristics of the drivers, and so on. A random sample of 400 policies written on single persons revealed 120 had at least one accident in the previous three-year period. Similarly, a sample of 600 policies written on married persons revealed that 150 had been in at least one accident. At the .05 significance level, is there a significant difference in the proportions of single and married persons having an accident during a three year period? Determine the p-value.
What type of statistical study is most likely to lead to an answer to the following questions? If they study is an experiment, identify the control and treatemnet groups, and discuss whether single-or double-blinding is necessary. If the study is observational, state whether it is a retroperspective studyso, identify the cases and controls. Which of eight airlines has the highest customer satisfaction?
The accompanying table shows results of challenged referee calls in a major tennis tournament. Use a 0.05 significance level to test the claim that the gender of the tennis player is independent of whether a call is overturned.
