Question

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 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 population distribution, use the Kruskal-Wallis Test to test for significant differences among the calorie content of these three candies.

State the null and alternative hypotheses.

H₀: Median_MM = Median_KK = Median_MW
H_a: Median_MM ≠ Median_KK ≠ Median_MW

H₀: Median_MM ≠ Median_KK ≠ Median_MW
H_a: Median_MM = Median_KK = Median_MW    

H₀: All populations of calories are identical.
H_a: Not all populations of calories are identical.

H₀: Median_MM = Median_KK = Median_MW
H_a: Median_MM > Median_KK > Median_MW

H₀: Not all populations of calories are identical.
H_a: All populations of calories are identical.

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.)

p-value =

At a 0.05 level of significance, what is your conclusion?

Reject H₀. There is not sufficient evidence to conclude that there is a significant difference among the calorie content of these three candies

.Do not reject H₀. There is not sufficient evidence to conclude that there is a significant difference among the calorie content of these three candies.     

Do not reject H₀. There is sufficient evidence to conclude that there is a significant difference among the calorie content of these three candies.

Reject H₀. There is sufficient evidence to conclude that there is a significant difference among the calorie content of these three candies.
