A) What do the treatments represent? How many treatments are there? Based on the information given in the problem setup, how do you know that is the number of treatments? B) What is the degrees of freedom for Error? Explain two reasons, based on the problem setup and ANOVA table, that you know this is the value for dfg. C) Calculate the MST (means square for treatment) and the MSE (means square for error).. Show your work. D) Calculate the F-Statistic. Show your work. E) Write the null and alternative hypothesis using correct notation. The question is stated in the problem setup. F) Using a 5% significance level is there sufficient evidence to support the alternative hypothesis? Explain using the p-value. G) Given a difference significant enough to warrant acceptance of the alternative hypothesis, can you conclude from the information provided that all four lists have different average number of words heard clearly? Explain your answer and reasoning. Based upon the following ANOVA table, computed using data on the number of words heard clearly when spoken in a noisy background from lists of differing suspected difficulty.___ different lists were considered. Is there sufficient evidence to conclude that the number of words heard clearly is not the same for the __ different lists? An equal number of samples from ____ different lists, for a total of 96 samples, was taken. You should note that the TOTAL DF is 95, which is N - 1, and error is N - k.
