A Researcher Wants to Determine the Difference in Scores for Three

A researcher wants to determine the difference in scores for three dentist clinics by the patients' responses. The scores (from 0 to 10) were taken from the official websites of each clinic for the study. These are the data of the scores. Conduct the Kruskal-Wallis test and make a conclusion about the acceptance or rejection of the null hypothesis. Use α = 0.05.

A) The test statistic is KW = 3.68, it is less than the critical value forα = 0.05 and therefore we fail to reject the null hypothesis that all clinics have the same scores.
B) The test statistic is KW = 8.19 , it is less than the critical value for α = 0.05 and therefore we fail to reject the null hypothesis that all clinics have the same scores.
C) The test statistic is KW = 3.68, it is more than the critical value for α = 0.05 and therefore we reject the null hypothesis that all clinics have the same scores.
D) The test statistic is KW = 8.19, it is more than the critical value for α = 0.05and therefore we reject the null hypothesis that all clinics have the same scores.
