She selects a random sample of 35 drivers over the age of 60 and nds that the mean number of miles driven is 23.2. The population standard deviation is 3 miles. At :1 = 0.01, is there sufcient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the Pvalue method with tables. State the hypotheses and identify the claim. HOE] amt] The hypothesis test is a (Choose one) I test. Find the Pvalue. Round the answer to at least four decimal places. Pvalue = [:1 Part 2 of 5 Compute the test value. Always round z score values to at least two decimal places. Z =Make the decision. Summarize the results. Were is met drivers over 60 years old drive less than 24 miles per day, on average
