Chapter 11: Q. 130 (page 670)

a. Explain why a goodness-of-fit test and a test of independence are generally right-tailed tests.

b. If you did a left-tailed test, what would you be testing?

Short Answer

Expert verified

a. the test statistic is large and the null hypothesis will be rejected.

b. if the data fits the distribution 鈥渢oo well鈥� or is too perfect.

Step by step solution

01

Given information

A goodness-of-fit test and a test of independence are generally right-tailed tests. Checking test statistics.

Checking null hypothesis.

02

Explanation (Part a)

A goodness-of-fit test and a test of independence are for the most part right-tailed tests, in light of the fact that the test measurement is generally sure and on the off chance that the normal and noticed values are not near one another, the test measurement is huge and the invalid theory will be dismissed.

03

Explanation (part b)

If we did a left-tailed test, testing to see if the data fits the distribution 鈥渢oo well鈥� or is too perfect.

What are the null and alternative hypotheses for a math teacher who sees if two of her classes have the same distribution of test scores.

A market researcher wants to see if two different stores have the same distribution of sales throughout the year. What type of test should he use?

Teachers want to know which night each week their students are doing most of their homework. Most teachers think that students do homework equally throughout the week. Suppose a random sample of 56 students were asked on which night of the week they did the most homework. The results were distributed as in Table 11.8.SundayMondayTuesdayWednesdayThursdayFridaySaturdayNumber ofStudents1181071055

From the population of students, do the nights for the highest number of students doing the majority of their homework occur with equal frequencies during a week? What type of hypothesis test should you use?

Use a solution sheet to solve the hypothesis test problem. Go to Appendix E for the chi-square solution sheet. Round expected frequency to two decimal places.

An archeologist is calculating the distribution of the frequency of the number of artifacts she finds in a dig site. Based on

previous digs, the archeologist creates an expected distribution broken down by grid sections in the dig site. Once the site has been fully excavated, she compares the actual number of artifacts found in each grid section to see if her expectation was accurate.
