- A Researcher Would Like To Conduct A Hypothesis Test To Determine If The Mean Age Of Faculty Cars Is Less Than The Mean 1 (28.1 KiB) Viewed 49 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 value of the test statistic if the difference is taken as student faculty? Round your final answer to two decimal places and do not round intermediate steps.
