Reference no: EM1393402

A random sample results in 1 = 20 with n1 = 100. The population standard deviation is σ1 = 6. Another sample was selected independently resulting in 2 = 22 with n2 = 100. The population standard deviation is σ2 = 7. Test that the population means differ using a 1% significance level.
