What are the independent and dependent variables for the question below?

A company came up with five different car waxes (A, B, C, D, E) and conducted an experiment to determine if they are equally strong. Specifically, in the experiment cars of three different brands (C1, C2, C3) were waxed with the products and repeatedly run through carwash until the wax coating showed signs of deterioration. Above data shows the number of times each car went through carwash before its wax deteriorated. Formulate the null and the alternative hypotheses and at .05 significance level conduct the appropriate statistical test to determine if all five waxes were equally effective?

	A	B	C	D	E
C1	32	26	24	22	21
C2	34	25	22	19	20
C3	36	27	26	22	19
