A store sells three different clothing designs and has recorded sales of each over five different 24-hour periods:

Design A Design B Design C

16 33 23

18 31 27

19 37 21

17 29 28

13 34 25

Use the Kruskal-Wallis H test and the Chi-Square table at the 0.05 level to compare the three designs.

Expert Solution

Analysis:

The null hypothesis, ho: there is no significant difference in the median sales between Design A, B, and C.

An alternative hypothesis, h1: at least one of the median sales between design A, B and C differ significantly.

With chi-square (2) = 12.5, p<5%, I reject the null hypothesis and conclude that at least one of the median sales between design A, B and C differ significantly.
