Question

1. What hypothesis ( null and alternative) are implied in this problem? Write down the hypothesis 2. Test for any significance difference between the mean out level of 6 treatments. Using a significance level of 0.05 the following results In an experiment designed to test the output level of 6 different treatments,t were obtained: SST 400, SSB-150, nr-36. We are willing to test if there is a significant difference between treatments d is also called Note: SST is Sum of Squares Total. SSB is Sum of Squares Between Treatme SSTR (Sum of Squares due to Treatment). nr is the total number of observations. nts an

Explanation / Answer

H0: There is no difference between treatments.

Ha: There is significant difference between the treatment.

Test statistics

SSR = SST - SSB = 250

MSS = SS / DF

F = MSB / MSR

ANOVA Table

Source DF SS MSS F P

SSB k-1=5 150 30 3.6 0.011417

SSR n-k=30 250 8.333

SST n-1=35 400

Since p value < 0.05 level, we have sufficient evidence to reject H0.

We conclude that at 0.05 level, there is enough evidence to support the claim that there is significant difference

between treatments.
