hello, please i need an urgent help to answer those three questions and the explication of each answer :

1) To determine whether the test statistic of ANOVA is statistically significant, it can be compared to a critical value. What two pieces of information are needed to determine the critical value?

a. sample size, number of groups

b. mean, sample standard deviation

c. expected frequency, obtained frequency

d. Mean square between groups, Mean square within the groups

2) When conducting a one-way ANOVA, the _______ the between-treatment variability is when compared to the within-treatment variability, the _______ the value of FDATA will be tend to be.

a. smaller, larger

b. smaller, smaller

c. larger, larger

d. smaller, more random

e. larger, more random

3)Suppose the critical region for a certain test of the null hypothesis is of the form F > 9.48773 and the computed value of F from the data is 1.86. Then:

a. H0 should be rejected.

b. The significance level is given by the area to the left of 9.48773 under the appropriate F distribution.

c. The significance level is given by the area to the right of 9.48773 under the appropriate F distribution. The hypothesis test is two-tailed

e. None of these

I Know that the responses are available on google but i need to be sure of the answers and especially i need an explication of it.

Thank you
