Use the Kruskal-Wallis test and a = 0.05 to determine whether there is a significant difference among the ratings for the products.
State the null and alternative hypotheses.
O H,: Median, * Median, + Median,
H: Median, = Median, = Median,
O H: Not all populations of product ratings are identical.
H: All populations of product ratings are identical.
O Ho: All populations of product ratings are identical.
H: Not all populations of product ratings are identical.
O Ho: Median, = Mediang = Medianc
H: Median, + Median, + Medianc
O Hg: Median, - Mediang = Medianc
H: Mediana < Mediang > Median,
Find the value of the test statistic.
