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
210 205 208
230 235 202
240 225 190
250 220 180

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: Not all populations of calories are identical.
Ha: All populations of calories are identical.H0: All populations of calories are identical.
Ha: Not all populations of calories are identical.    H0: MedianMM = MedianKK = MedianMW
Ha: MedianMM > MedianKK > MedianMWH0: MedianMM ≠ MedianKK ≠ MedianMW
Ha: MedianMM = MedianKK = MedianMWH0: MedianMM = MedianKK = MedianMW
Ha: MedianMM ≠ MedianKK ≠ MedianMW

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?

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

The military often uses high-density metals in munitions because these metals are better able to penetrate armor. Magness (1994) conducted an obserational study of seven different high-density metals in which he measured the Rockwell hardness (the regressor) and the Young's Modulus (the response) for a single specimen for each metal. The Young's Modulus is the ratio of simple tension stress to the resulting strain parallel to the tension. Normally, we expect Young's modulus to increase as the Rockwell hardness increases....

Salt-free diets are often prescribed to people with high blood pressure. The following data values were obtained from an experiment designed to estimate the reduction in diastolic blood pres- sure as a result of consuming a salt-free diet for 2 weeks. Assume diastolic readings to be normally distributed. (a) Calculate a 90% confidence interval for the mean reduction. (b) Is there evidence that diastolic blood pressure is reduced by having salt-free diets, use α = 0.05. Patients A. B. C....
