Seat Belt Use In a random sample of 182 men, 65 said they used seat belts. In a random sample of 289 women, 75 said they used seat belts. Test the claim that men are more safety conscious than women, at a 0.10. Use the Pvalue method and use p for the proportion of men who use seat belts and round all intermediate calculations to at least three decimal places.

1. Explain how different statistical measures of individual risk help managers and business owners make better decisions. For your answer, consider the following statistical measures of risk: probability distributions, expected rates of return, historical rates, standard deviation, coefficient of variation, and Sharpe ratio.
How much customers buy is a direct result of how much time they spend in the store. A study of average shopping times in a large national houseware store gave the following information (Source: Why We Buy: The Science of Shopping by P. Underhill). Women with female companion: 8.3 min.Women with male companion: 4.5 min. Suppose you want to set up a statistical test to challenge the claim that a woman with a female friend spends an average of 8.3 minutes shopping in such a store. (a) What would you use for the null and alternate hypotheses if you believe the average shopping time is less than 8.3 minutes? Ho: ? = 8.3; H1: ? ≠ 8.3Ho: ? < 8.3; H1: ? = 8.3 Ho: ? = 8.3; H1: ? < 8.3Ho: ? = 8.3; H1: ? > 8.3 Is this a right-tailed, left-tailed, or two-tailed test? right-tailedtwo-tailed left-tailed (b) What would you use for the null and alternate hypotheses if you believe the average shopping time is different from 8.3 minutes?
