Answer:
Since the calculated value of F=0.20 does not fall in the critical region
F ≥ = 3.481 we reject the alternate hypothesis and accept the null hypothesis and conclude that there is no difference between the means of the 3 treatments.
Step-by-step explanation:
As the sample size are different we can run anova in the excel.
Part a)
The null and alternate hypotheses are
H0: μ1=μ2=μ 3 against the claim Ha: Not all three means are equal
The significance level ∝ is chosen to be 0.05
Part b)
The critical region is F≥ F(0.05,5,9) = 3.481
Part c) SST, SSE, and SS total
SS total= 144.933
SSE= 129.8333
SST= 15.1
A nova: Single Factor
SUMMARY
Groups Count Sum Average Variance
Column 1 3 32 10.67 4.33
Column 2 3 36 12 49
Column 3 3 40 13.33 4.33
Column 4 3 36 12 7
Column 5 2 25 12.5 0.5
Column 6 1 10 10 ----------
The missing value in the variance column does not account for because the excel uses the mean to perform analysis.
Part d)

Part e)
Since the calculated value of F=0.20 does not fall in the critical region
F ≥ = 3.481 we reject the alternate hypothesis and accept the null hypothesis and conclude that there is no difference between the means of the 3 treatments.
