Chapter 9: Q.28 (page 548)

You use technology to carry out a significance test and get a P-value of 0.031. The correct conclusion is

a. accept Haat data-custom-editor="chemistry" α=0.05 significance level.

b. reject H0at α=0.05 significance level.

c. reject H0at the α= 0.01 significance level.

d. fail to reject H0at the α= 0.05 significance level.

e. fail to reject Haat the α= 0.05 significance level.

Short Answer

Expert verified

The correct conclusion is option b. reject H0 at α=0.05 significance level.

Step by step solution

01

Introduction

A hypothesis is a proposed clarification for a peculiarity. For a theory to be logical speculation, the logical technique expects that one can test it.

02

Explanation

Given,

P-value = 0.031

Considering α=0.05, The p-value is less than α.

Hence H0is rejected

Considering α=0.01, The p-value is greater than α.

Hence it is correct.

Therefore option b. reject H0at α=0.05 significance level is correct

Taking stock An investor with a stock portfolio worth several hundred thousand dollars sued his broker due to the low returns he got from the portfolio at a time when the stock market did well overall.

The Minitab output below displays descriptive statistics for these data, along

with the results of a significance test.
