Question

Three admission test preparation programs are being evaluated. Suppose the scores obtained by a sample of 20 people who used the programs provided the following data.

Program
A	B	C
530	450	600
400	530	610
460	400	590
510	440	460
460	490	560
640	370	620
	550	570

Use the Kruskal-Wallis test to determine whether there is a significant difference among the three test preparation programs. Use ? = 0.05.

Find the value of the test statistic. (Round your answer to two decimal places.)

Find the p-value. (Round your answer to three decimal places.)

p-value =

State your conclusion.
