Question

Consider the following table:

	SS	DF	MS	F
Among Treatments	4109.12		1027.28	2.99
Error	?
Total	8570.85	17

Step 1 of 8:

Calculate the sum of squares of experimental error. Please round your answer to two decimal places.

Step 2 of 8:

Calculate the degrees of freedom among treatments.

Step 3 of 8:

Calculate the degrees of freedom of experimental error.

Step 4 of 8:

Calculate the mean square of the experimental error. Please round your answer to two decimal places.

Step 5 of 8:

What is the sum of squares of sample means about the grand mean? Please round your answer to two decimal places.

Step 6 of 8:

What is the variation of the individual measurements about their respective means? Please round your answer to two decimal places.

Step 7 of 8:

What is the critical value of F at the 0.10.1 level? Please round your answer to four decimal places, if necessary.

Step 8 of 8:

Is F significant at 0.10.1?

Answer 1

Source	SS	df	MS	F
treatment	4109.12	4	1027.28	2.99
error	4461.73	13	343.21
total	8570.85	17

Step 1 of 8:

sum of squares of experimental error. =8570.85-4109.12=4461.73

Step 2 of 8:

degrees of freedom among treatments =4109.12/1027.28 =4

Step 3 of 8:

degrees of freedom of experimental error =17-4 =13

Step 4 of 8:

mean square of the experimental error =343.21

Step 5 of 8:

sum of squares of sample means about the grand mean =4109.12

Step 6 of 8:

variation of the individual measurements about their respective means =4461.73

Step 7 of 8:

critical value of F =2.4337

Step 8 of 8: :Yes (since test statistic >critical value )
