Chapter 13: Q.6 (page 764)

There are five basic assumptions that must be fulfilled in order to perform a one-way ANOVA test.

State the null hypothesis for a one-way ANOVA test if there are four groups.

Short Answer

Expert verified

The null hypothesis for the four groups is given below:

H0:渭1=渭2=渭3=渭4

Where, 渭1is the mean of the first group,渭2is the mean of the second group,渭3is the mean of the third group and渭4 is the mean of the fourth.

Step by step solution

01

Step[ 1 Given Information

Five basic assumptions must be fulfilled to perform a one-way ANOVA test.

We have to state the null hypothesis for a one-way ANOVA test if there are four groups.

02

Explanation

The null hypothesis for a one-way ANOVA test is simply that, all the group population means are the same. The null hypothesis for the four groups is given below:

H0:渭1=渭2=渭3=渭4

Where,渭1is the mean of the first group, 渭2is the mean of the second group, 渭3is the mean of the third group and 渭4is the mean of the fourth.

King Manuel I, Komnenus ruled the Byzantine Empire from Constantinople (Istanbul) during the years 1145to 1180A.D. The empire was very powerful during his reign, but declined significantly afterwards. Coins minted during his era were found in Cyprus, an island in the eastern Mediterranean Sea. Nine coins were from his first coinage, seven from the second, four from the third, and seven from a fourth. These spanned most of his reign. We have data on the silver content of the coins:

Did the silver content of the coins change over the course of Manuel鈥檚 reign?

Here are the means and variances of each coinage. The data are unbalanced.
