Chapter 8: Q.93 (page 483)

Using the same p′ and n = 80, how would the error bound change if the confidence level were increased to 98%? Why?

Short Answer

Expert verified

The error bound would increase.

Step by step solution

01

Introduction

The error bound would increase.

If we assume that all factors remain constant, our confidence will rise.
If the area under the curve performs a wider interval and so generates a very huge error, the confidence level increases.

If we assume that all factors remain constant, our confidence will rise.

02

Explanation

The margin of error would widen. Assuming that all other variables remain constant, when the confidence level rises, the area under the curve corresponding to the confidence level expands, resulting in a wider interval and, consequently, a higher inaccuracy.
