=Test: Final Exam Question 25 of 25 This test: 25 point(s) possible This question: 1 point(s) possible Submit test Assume that Friday morning taxi-cab rises have times with a standard deviation of o = 9.9 minutes. A cab driver records times of rides during a Friday afternoon time period and obtains these statistics: n = 15, x = 17.8 minutes, s = 12.8 minutes. Use a 0.01 significance level to test the claim that these Friday afternoon times have greater variation than the Friday morning times. Assume that the sample is a simple random sample selected from a normally distributed population. Let o denote the population standard deviation of Friday afternoon cab-ride times. Identify the null and alternative hypotheses. HO : OC H : GV (Type integers or decimals. Do not round.) Identify the test statistic . ( Round to two decimal places as needed. ) Identify the P-value . (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. the null hypothesis.
