A medical researcher wishes to try three different techniques to lower cholesterol levels of patients with highcholesterol levels. The subjects are randomly selected and assigned to one of three groups. Group 1 is givenmedication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of sixweeks, each subject's cholesterol level is recorded. Use the printout from Minitab to make a decision andconcluesion about the mean cholesterol levels found in the groups after the different techniquess were applied.Use΅= 0.05. Group 1 9, 12, 11, 15, 13, 8 Group 2 8, 3, 2, 5, 4, 0 Group 3 6, 12, 4, 4, 9, 8 A) Hypothesis Ho : Ha : B) Decision to reject or fail to reject Ho based on the Minitab printout. C) Conclusion about the problem statement as it pertains to cholesterol and the groups.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
