Question

If we reject the null hypothesis in a one-wav ANOVA, there is evidence to suggest that at least two treatment means differ. (a) True (b) False In a two-way ANOVA, factor A is A is run at 6 leaves and factor B is run at 8 leaves, than the number of degrees of freedom for treatments is calculated to be 47. (a) True (b) False In a simple linear regression problem, based on a date set 16 ordered pairs (x, y), I = 1, 2..., 18, we use t-test to H_0: beta_1 = 0 vs. Ha-: bet_1notequalto 0 at the 0.05 level. Then the rejection region is given by |t| > 1.746. (a) True (b) False The lest is used to check if a linear statistical relationship exists between the response variable and at least one predictor variable is called the test for significance of regression. (a) True (b) False The trials of a multinomial experiment are dependent: that is, the outcome on one trial does affect the outcomes on other tribes. (a) True (b) False

Explanation / Answer

(6) True , we accept alternate hypothesis H1: at least two treatment means differ

(7)False

(8)false, 16 orderde pair will have error df=14 and critical t(0.05/2,14)=2.14 , this two tailed test

(9)False,

(10) True
