Question 8 7 points An Engineer wants to compare the effect of 4 chemical additive A1, A2, A3, M) on the amount of dangerous materiale removed from an industrial waste shton He run an experimental study using the different additives. He measured the amount of dangerous materials removed from samples of 100 ml of the industrial waste schition. There are summarired in the table below. Additive used Sample Size Sample Mean Sample STD A1 15 09 A2 16 0.6 A3 7 12 1.1 A4 7 12 0.9 Give your answers to three decimal places (example 45.543) 1) Compute the overall sample average 2) Fill in the Anova table below Source SS DF MS F Treatment 29.279 Error Total 3) Find the critical value for the 0.05 significance level: 4) is there any differences between the means amount of dangerous materials removed for the 4 additives? Ansia Iveso) since FO is (greater/ smaller than the critical value A3 AL 12 12 1.1 0.9 Glve your answers to three decimal places (example 45.543) 1) Compute the overall sample average 2 full in the Anova table below Source SS DF MS Treatment 29.279 I Error For Bank Total 3) Find the critical value for the 0.05 significance level: 4) is there any differences between the means amount of dangerous materials removed for the 4 additives? Answer: lyeso) since FO is greater/ smaller than the critical value 5) For 0,05 significance, find the LSD value that we will use to compare additive 1 and 3. 6) In terms of their ability to remove dangerous materials, Is additve A1 different from Additive A3 ? (yeso) Question 8 7 points An Engineer wants to compare the effect of 4 chemical additive A1, A2, A3, M) on the amount of dangerous materiale removed from an industrial waste shton He run an experimental study using the different additives.
