Question

b and d are correct

(1 point) Suppose you are using a completely randomized design to study some phenomenon. There are Afive treatment levels and a total of 55 people in the study. Each treatment level has the same sample size. (a) Complete the following ANOVA table. P-value Source Degrees of Freedom Treatment 1 : Sum of Squares 583.39 Mean Square 583.39 18.343 31.804 00 Error 53 !! 972.18 ! Total 54 1555.57 (b) Formulate the appropriate statistical hypotheses. A. H : The treatments make no difference on the response variable HA : The treatments make a significanta cant difference on the response variable B. Ho : The treatments make a significantAcant difference on the response variable HA : The treatments make no difference on the response variable (c) Find the critical value when a is 5%: 4.023 00 (d) Using an a of 5%, Do the treatments make a significant difference on the response variable? Yes. v.

Answer 1

Ans:

a)

Source	DF	SS	MS	F	p-value
Between	4	583.39	145.8475	7.501054	0.0001
Within	50	972.18	19.4436
Total	54	1555.57

b)Option A is correct.

c)

critical F value=FINV(0.05,4,50)=2.557

d)Yes

Reject the null hypothesis and conclude that there is significant difference in the response variable.
