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
This is a combination problem.
The formula is n! / (r!(n-r)!
where n is the total number of people and r is the number of people to be picked.
n = 15, r = 4
15! / (4!(15-4)!)
15! / (4!*11!)
Total combinations = 1,365
2x + y = - 8
y = - 2x - 8
Since we are looking for a parallel line, we use the same slope of - 2x.
y = - 2x + b
Plug in your given point.
5 = - 2(- 3) + b
5 = 6 + b
5 - 6 = b
-1 = b
Your equation is y = - 2x - 1
