A researcher wishes to try three different techniques to lower the pressure of individuals high blood diagnosed with blood pressure. The subjects are randomly assigned to three groups; the first group takes medication, the second group exercises,and the third group follows a special diet. After four weeks, the reduction in each person's blood pressure is recorded. At 0.05 level of significance, test the claim that there is no difference among the means. Hint: Tabulated value = 3.89 The data are shown: exercise diet medication 10 6 12 12 15 13 4 Then: The decision is to accept the null hypothesis. OThe decision is to increase sample size. OThe decision is to decrease sample size. O The decision is to reject the null hypothesis.

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.
