Homework Answers

Answer #1

Let p be the fraction (or proportion) of tenth grade students that have reading skills at or below the eighth grade level.

Here our goal is is to estimate p

We estimate p with

n = 2252 (sample size)

Let x denote number of students who read at or below the eighth grade level

x = 495

Estimate of p is

Answer: Estimate of the proportion of tenth graders reading at or below the eighth grade level is 0.220
