◦ Both samples were randomly and independently selected from their respective populations.
◦ Both populations have approximate normal distributions.
◦ The population variances are equal.
◦ All of the above are necessary.

Question 2

Determine whether the sample sizes are large enough to conclude that the sampling distributions are approximately normal.
