Answer 1

Answer:

Step-by-step explanation:

The pediatrician said that the z-score for the boy's height, relative to other 2-year-olds in the country, was 1.59

He explains to the parents of the boy, that the extreme 5% of cases often require special attention.

(A) Does this child fall into that group?

Yes, this child falls into that group. He is among the extreme 5% of cases at the tail of the distribution.

(B) What do you need to assume about the heights of 2-year-olds, in order to find your answer to part (A)?

Assume that the distribution of heights is skewed, the heights are independent of one another, and the number of heights is very large.
