15. Inference review, problem 15 Aa Aa Suppose you are the owner of a chain of pizza restaurants. You want to expand operations to whichever of the cities of Decatur and Springfield has the highest average income per capita. You collect data on a random sample of residents from both cities, asking what is their yearly income (measured in dollars). The p-value for the F-test was 0.231. Given this information, what test would be most appropriate? O A z-test for the difference in means A z-test for population proportion O A chi-squared test for variance O A z-test for difference in proportions O An F-test for difference in variances O A paired sample t-test for difference in means A z-test for the mean O An independent samples t-test for difference in means (equal variances) O A t-test for the mean O An F-test for difference in means O An independent samples t-test for difference in means (unequal variances)Suppose you are the owner of a chain of pizza restaurants. You believe that the manager at the Champaign branch has a very irregular performance. You gather monthly data on profits for the Champaign branch of your restaurant (measured in dollars and cents). Given this information, which of the following tests would be most appropriate to use to test whether the volatility in profits for the Champaign branch is more than $20,000? O A z-test for the difference in means O An independent samples t-test for difference in means (equal variances) O A z-test for population proportion A z-test for the mean O A chi-squared test for variance O An F-test for difference in variances An F-test for difference in means O A paired sample t-test for difference in means O A t-test for the mean O An independent samples t-test for difference in means (unequal variances) O) A z-test for difference in proportionsSecure | https://www.mathxl.com/Student/PlayerTest.aspx?testld=173738518&cente Math 1314.019 College Algebra: Spring 2018 Quiz: Quiz 4.2 Exponential Functions This Question: 1 pt Solve the equation.
