Students of two sections of a history course took a common final examination. The course instructor examines the variance in scores between the two sections. He selects random samples of n₁ = 11 and n₂ = 16 with sample variances of = 400 and = 200, respectively. Suppose you obtain a 95% confidence for the ratio of the population variances. Which of the below allows you to conclude the first variance is smaller than the second variance? A) The entire interval is less than 1 B) The interval captures 1 C) The entire interval is more than 1 D) None of the above
