- A Researcher Would Like To Conduct A Hypothesis Test To Determine If The Mean Age Of Faculty Cars Is Less Than The Mean 1 (25.98 KiB) Viewed 38 times
A researcher would like to conduct a hypothesis test to determine if the mean age of faculty cars is less than the mean age of student cars. A random sample of 25 student cars had a sample mean age of 7 years with a sample variance of 20, and a random sample of 32 faculty cars had a sample mean age of 5.8 years with a sample variances of 16. What is the critical value of the rejection region if the difference is taken as student - faculty and the test is conducted using a 5% significance level?
