Daily Driving The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60drive less than 24miles per day. She selects a random sample of 25 drivers over the age of 60 and finds that the mean number of miles driven is 23.4. The population standard deviation is 4.1miles. At =α0.01, is there sufficient 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 critical value method with tables. State the hypotheses and identify the claim with the correct hypothesis. :H0 ▼not claim or claim??? :H1▼not claim ot claim??? This hypotheses test is a two tailed or one tailed??? test.
