Consider a hypothesis test of difference of means for two independent populations x1 and x2. Suppose that both sample sizes are greater than 30 and that you know ?1 but not ?2. Is it standard practice to use the normal distribution or a Student's t distribution? Use the Student's t distribution because both sample sizes are greater than 30. Use the normal distribution because we do not know ?2. Use the normal distribution because both sample sizes are greater than 30. Use the Student's t distribution because we do not know ?2.
