The better-selling candies are often high in calories. Assume that the following data show the calorie content from samples of M&M's, Kit Kat, and Milky Way candies.
M&M's | Kit Kat | Milky Way |
---|---|---|
220 | 215 | 200 |
210 | 205 | 208 |
240 | 245 | 202 |
250 | 235 | 190 |
220 | 230 | 180 |
Test for significant differences among the calorie content of these three candies.
State the null and alternative hypotheses.
H0: MedianMM= MedianKK= MedianMW Ha: MedianMM> MedianKK> MedianMW
H0: MedianMMMedianKKMedianMW Ha: MedianMM= MedianKK= MedianMW
H0: Not all populations of calories are identical. Ha: All populations of calories are identical.
H0: MedianMM= MedianKK= MedianMW Ha: MedianMMMedianKKMedianMW
H0: All populations of calories are identical. Ha: Not all populations of calories are identical.
Find the value of the test statistic. (Round your answer to two decimal places.)
Find thep-value. (Round your answer to three decimal places.)
p-value =
At a 0.05 level of significance, what is your conclusion?
RejectH0. There is sufficient evidence to conclude that there is a significant difference among the calorie content of these three candies.
Do not rejectH0. There is sufficient evidence to conclude that there is a significant difference among the calorie content of these three candies.
RejectH0. There is not sufficient evidence to conclude that there is a significant difference among the calorie content of these three candies.
Do not rejectH0. There is not sufficient evidence to conclude that there is a significant difference among the calorie content of these three candies.
