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" 伪=0.05 significance level.

b. reject H0at 伪=0.05 significance level.

c. reject H0at the 伪= 0.01 significance level.

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

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

Short Answer

Expert verified

The correct conclusion is option b. reject H0 at 伪=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 伪=0.05, The p-value is less than 伪.

Hence H0is rejected

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

Hence it is correct.

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

We hear that listening to Mozart improves students鈥� performance on tests. Maybe pleasant odors have a similar effect. To test this idea, 21subjects worked two different but roughly equivalent paper-and-pencil mazes while wearing a mask. The mask was either unscented or carried a floral scent. Each subject used both masks, in a random order. The table below gives the subjects鈥� times with both masks.

Better barley Does drying barley seeds in a kiln increase the yield of barley? A famous experiment by William S. Gosset (who discovered the t distributions) investigated this question. Eleven pairs of adjacent plots were marked out in a large field. For each pair, regular barley seeds were planted in one plot and kiln-dried seeds were planted in the other. The following table displays the data on yield (lb/acre).

(b) Perform an appropriate test to help answer the research question. Assume that the Random condition is met. What conclusion would you draw?

(a) State hypotheses for a significance test to determine whether first responders are arriving within 8 minutes of the call more often. Be sure to define the parameter of interest.
