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. Ho: H (1) H: μ (2) (Type integers or decimals. Do not round.) Identify the t-statistic. to = (Round to two decimal places as needed.) Identify the P-value.

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.

9. The GRE is a test that is widely used by many Universities throughout the country to determine graduate (Masters, Doctorate, Professional, etc) admissions. It consists of three parts: Verbal Reasoning, Quantitative Reasoning, and Analytical Writing (Source: www.ets.org). The 2014-15 scores for the Analytical Writing portion of the GRE is approximately normal with a mean score u=3.5 and standard deviation o=0.9. Use the 68-95-99.7 rule to draw the distribution of the data. a) 68% of the Analytical Writing scores fall between and b) 95% of the Analytical Writing scores fall between and c) 99.7% of the Analytical Writing scores fall between and d) What percent of GRE Analytical Writing scores lie above 2.6? e) What percent of GRE Analytical Writing scores lie below 5.3? f) What percent of GRE Analytical Writing scores lie below 1.7? g) What percent of GRE Analytical Writing scores lie between 1.7 and 6.2? h) How much score do you need to be in the top 16%? i) How much score will push…
