The Degree of freedom of Numerator is 2

See the step by step solution

Step by Step Solution

TABLE OF CONTENTS :
TABLE OF CONTENTS

Step  1 Given Information

We have to find the df for the numerator

Step 2 Explanation

Use the table given below of weight for the different groups to calculate the degree of freedom for the numerator

Step 3: Calculation

To calculate the degree of freedom for the numerator, use Ti-83 calculator. For this, click on STAT → press 1→ EDIT, then put the above-given weights of different groups' data into the list L 1, L 2 and L 3. The screenshot is given below:

Step 4 Calculation -2

Now-Again press STAT → arrow over the TESTS → arrow down to ANOVA →Press var then select1, press var then select 2, press var then select 3 to fill the values of L 1, L 2 and L 3. The screen shot is given as below:

Step 5 

Press ENTER. The screenshot of the obtained output of calculated degree of freedom for the numerator is given as below.

The Degree of freedom of Numerator is 2

Assume that all distributions are normal, the four population standard deviations are approximately the same, and the data were collected independently and randomly. Use a level of significance of 0.05.

What is the Mean Square Factor?

King Manuel I, Komnenus ruled the Byzantine Empire from Constantinople (Istanbul) during the years 1145 to 1180 A.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’s reign?

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