According to a report on consumer fraud and identity theft, 22% of all complaints for a year were for identity theft. In that year, Ohio had 825 complaints of identity theft out of 3452 consumer complaints. Does this data provide enough evidence to show that Ohio had a higher proportion of identity theft than 22%? Test at the 1% level. State the hypotheses. Ho: p? v Ha: p|? v Calculate the test statistic. Round to four decimal places. Calculate the standardized test statistic. Round to three decimal places.

There is a lot of interest in the relationship between studying music and studying math. We will look at some sample data that investigates this relationship. Here are the Math SAT scores from 8 students who studied music through high school and 12 students who did not.

Each person in random samples of 247 male and 263 female working adults living in a certain town in Canada was asked how long, in minutes, his or her typical daily commute was. Is there enough evidence to show that there is a difference in mean commute times for male and female working residents of this town? (Use males-females.) Sample size 247 Male 30.6 5 24.0 Sample size 263 Female x 28.3 Find the test statistic. (Round your answer to two decimal places.) t = Find the df. (Round your answer down to the nearest whole number.) df = S 24.3 Use technology to find the P-value. (Round your answer to four decimal places.) P-value = Is there enough evidence to show that there is a difference in mean commute times for male and female working residents of this town? Use a significance level of 0.05. O Yes O No
Topic: Formulating the appropriate null and alternative hypotheses on a population mean and Identifying the appropriate form of the test statistics A driver claims that their average net take-home pay in a day is $250. Mr. Tim wants to prove this claim by surveying 15 drivers of the town. The values obtained are $280, $270, $250, $240, $260, $280, $290, $300, $230, $250, $250, $260, $220, $250 and $260. Is there a reason to believe that the average net take-home pay of a driver in the town is $250.00? Assume that the net weight is normally distributed with unknown population variance. Find the: 1.) Null Hypothesis: ______________ 1.1.) In symbol, Ho: µ = __________ 2.) Alternative Hypothesis: _________ 2.2.) In symbol, Ha: µ = ___________ 3.) Test Statistic to be used: _______
