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 в 540 450 600 400 540 | 620 480 400 57o 520 410 480 480 470 580 610 360 630 550 560 Use the Kruskal-Wallis test to determine whether there is a significant difference among the three test preparation programs. Use a = 0.05. State the null and alternative hypotheses. O Ho: Mediana = Mediang = Medianc H3: Mediana + Mediang + Medianc O Ho: Mediana = Mediang = Medianc Hg: Median, > Median, < Medianc O Ho: All populations of test scores are identical. H: Not all populations of test scores are identical. O Ho: Not all populations of test scores are identical. H: All populations of test scores are identical. O Ho: Median, # Mediang + Medianc H3: Mediana = Mediang = Median c 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.)
