Answer: c. 10
Step-by-step explanation:
Given : An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment.
For this study, the three sample means are, M1 = 1, M2 = 2, and M3 = 3.
Grand mean = [All sample have equal elements]
For ANOVA,
, where i= 1, 2 , 3
Hence,the value would be obtained for .
hence, the correct answer = c. 10
The sum of slopes of lines b and c are 0
N is the same as 17, so it equals 17.
