A random sample of 49 measurements from one population had a sample mean of 16, with sample standard deviation 3. An independent random sample of 64 measurements from a second population had a sample mean of 18, with sample standard deviation 4. Test the claim that the population means are different. Use level of significance 0.01.
(c) Compute
Compute the corresponding sample distribution value. (Test the difference μ1− μ2. Round your answer to three decimal places.)
