- If you wanted to determine whether mean levels of blood glucose were different according to gender and age a one-way ANOVA would be an appropriate test to perform. True FalseIf correlation does not imply causation, what does it imply?A consumer advocacy group is doing a large study on car rental practices. Among other things, the consumer group would like to do a statistical test regarding the mean monthly mileage, u, of cars rented in the U.S. this year. The consumer group has reason to believe that the mean monthly mileage of cars rented in the U.S. this year is different from last year's mean, which was 2750 miles. The group plans to do a statistical test regarding the value of u. It chooses a random sample of monthly mileages and computes the mean of the sample to be 2900miles and the standard deviation to be 800 miles. Based on this information, answer the questions below. What are the null hypothesis (H,) and the alternative hypothesis (H,) that should be used for the test? Ho H is? u is ? In the context of this test, what is a Type II error? A Type II error is ? the hypothesis that u is ? when, in fact, u is ? Suppose that the group decides to reject the null hypothesis. What sort of error might it be…

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 708.2. 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 39 high-income individuals and found the sample mean credit score to be 725.5 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.
