Question

In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five treatments (a total of 65 observations). The following information is provided.

​

SSTR = 200 (Sum of Squares Due to Treatments)

SST = 800 (Total Sum of Squares)

​

If we want to determine whether or not the means of the five populations are equal, the p-value is

	a.	between .01 to .025.
	b.	less than .01.
	c.	between .025 to .05.
	d.	greater than .10.

Answer 1

SSE=SST-SSTR

=800-200

=600

P value =0.0015....................by using Excel =FDIST(5,4,60)

b.	less than .01.
