Compare your sample estimate to the current mean gas in the State of Ohio. Find the mean price of gasoline in the State of Ohio. You might try this GasBuddy website. Set up a null and alternative hypothesis to see if your sample for Dayton is enough to prove that the population mean gasoline price in Dayton is different than the mean price in Ohio. Test the hypotheses. Show your work. Using a significance level of 0.05, what is your conclusion?
Part 3 - Compare your sample estimate to the current mean gas in the U.S. What is the mean price of gasoline in the U.S.? You might try reading the graph on this GasBuddy website. Set up a null and alternative hypothesis to see if your sample for Dayton is enough to prove that the population mean price in Dayton is different than the mean price in the U.S. Test the hypotheses. Show your work. Using a significance level of 0.05, what is your conclusion?
