6) Successful hotel managers must have certain personality traits that may seem contradictory, such as being compassionate yet forceful. A certain personality test has a scale of 1 to 7. A sample of 148 male general managers of 5-star hotels had a mean score of 5.29. The mean score for the general male population is 5.19 with a standard deviation of 0.78 We wish to determine if hotel managers have a statistically significantly different score from the general male population. a) State the null and alternative hypotheses in terms of the mean score. b) Calculate the z test statistic. c) Find the P-value for your z-statistic. Using a 5% a-level, what can you conclude about the personalities of male hotel managers in comparison to the general male population?

5. A credit score is used by credit agencies (such as mortgage companies and banks) to assess the creditworthiness of individuals. Values range from 300 to 850, with a credit score over 700 considered to be a quality credit risk. According to a survey, the mean credit score is 702.9. A credit analyst wondered whether high-income individuals (incomes in excess of $100,000 per year) had higher credit scores. He obtained a random sample of 32 high-income individuals and found the sample mean credit score to be 719.1 with a standard deviation of 80.6. Conduct the appropriate test to determine if high-income individuals have higher credit scores at the a = 0.05 level of significance. State the null and alternative hypotheses.

12) A state fish hatchery raises trout for stocking streams and lakes. The size of the fish at release time can be controlled to a fair degree by varying the rate of feeding. The target is a mean of 10 ounces; if the fish are too small, those who catch the fish aren’t happy. A random sample of 75 fish were weighed at time of release and it was determined that the mean was 9.66 ounces with a standard deviation of 0.86 ounces. Test to determine if the fish being released have a population mean less than 10 ounces at the 0.01 significance level.
