Question 1

We sampled 100 men and 100 women and asked: "Do you think the environment is a major concern?" Of those sampled, 67 women and 53 men responded that they believed it is. For the confidence interval procedure to work properly, what additional assumptions must be satisfied?

◦ 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.
