One-way ANOVA is performed on three independent samples with n1 =6, n2 =7, and n3 =8. The critical value obtained from the F-table for this test at the 5% level of significance equals:

a.

29.45.

b.

4.56.

c.

3.55.

d.

39.45. Ques 2) A regression analysis between sales (in $1000) and advertising (in $) resulted in the following least squares line: = 80,000 + 5*x. (The meaning of the parenthetical $ amounts is that if you enter x as the number of dollars, the equation will give you the resulting sales in thousands of dollars.) The equation implies that an: A) increase of $5 in advertising is expected to result in an increase of $25,000 in sales.

B)increase of $5 in advertising is expected to result in an increase of $5,000 in sales.

C) increase of $1 in advertising is expected to result in an increase of $80,005 in sales.

D) increase of $1 in advertising is expected to result in an increase of $5 in sales.
