This question is scored in three sections . Section 1 consists of part (a); Section 2 consists of the outlier determination in part (b); Section 3 consists of the boxplot sketch in part (b) and part (c). Each section is scored as essentially correct (E), partially correct (P), or incorrect (I). Section 1. Help students recognize two ideas: The greater the sample size, the closer the Normal approximation is to the binomial distribution. The closer that p is to 0.5, the more symmetric the binomial distribution, and therefore closer to Normal. These two ideas are combined to form the Large counts condition np > 10 and n (1 – p) > 10.
