Daily DrivingThe average number of miles a person drives per day is24. A researcher wishes to see if people over age60drive less than24 miles per day. She selects a random sample of27drivers over the age of60and finds that the mean number of miles driven is22.2. The population standard deviation is3.7miles. At= 0.05, is there sufficient evidence that those drivers over60years old drive less than24 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_____ claim /not claim

H1 _____ claim /not clame

- The hypothesis test is a __________test.

a. one-tailed

b. two-tailed

-Find the critical value(s). Round the answer to at least two decimal places. If there is more than one critical value, separate them with commas.

Critical value(s) = ___________

-Compute the test value. Always roundz score values to at least two decimal places.

z =________________

Make the decision.___________________the null hypothesis

a. reject

b. do not reject

-Summarize the results. There is______________that drivers over60years old drive less than24 miles per day, on average.

a . not enough evidence to support the claim

b. enough evidence to support the claim

c. enough evidence to reject the claim

d. not enough evidence to reject the claim
