The better-selling candies are often high in calories. Assumethat the following data show the calorie content from samples ofM&M's, Kit Kat, and Milky Way II.
M&M's | Kit Kat | Milky Way II |
---|
250 | 245 | 200 |
230 | 225 | 228 |
240 | 215 | 202 |
220 | 235 | 190 |
250 | 210 | 180 |
Assuming we don't know about the shape of the populationdistribution, use the Kruskal-Wallis Test to test for significantdifferences among the calorie content of these three candies.
State the null and alternative hypotheses.
H0: MedianMM =MedianKK = MedianMW
Ha: MedianMM ≠MedianKK ≠MedianMW
H0: MedianMM ≠MedianKK ≠MedianMW
Ha: MedianMM = MedianKK =MedianMW   ÂÂ
H0: All populations of calories areidentical.
Ha: Not all populations of calories areidentical.
H0: MedianMM =MedianKK = MedianMW
Ha: MedianMM >MedianKK > MedianMW
H0: Not all populations of calories areidentical.
Ha: All populations of calories areidentical.

At a 0.05 level of significance, what is your conclusion?
Reject H0. There is not sufficient evidenceto conclude that there is a significant difference among thecalorie content of these three candies
