Source Degrees of Sum of the Mean Square Test statistic freedom squares value Between 6 36.25 Within 195.75 F = - Total 24 b) How many populations do you have based on the data from the table? c) Find the critical value(s) for a = 2.5%. What distribution do you use? Show rejection region on a picture. d) Test if the means of the populations are not equal using the significance level a=2.5%. State the hypothesis. Make a conclusion
