Use software to conduct the analysis of variance test. Use a significance level of 0.05 to test the null hypothesis.
-A medical researcher wishes to try three different techniques to lower blood pressure of patients with high blood pressure. The subjects are randomly selected and assigned to one of three groups. Group 1 is given medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six weeks, each subject's blood pressure is recorded.Do the data indicate that there is a difference in mean blood Pressure for the three groups? $$\begin{array} { c c c }

The analysis of variance (ANOVA) test is used to determine if there are statistically significant differences between the means of three or more independent groups. Given the scenario and the data provided, if an ANOVA test is conducted at a significance level of 0.05 and it indicates a p-value less than 0.05, it means there is enough evidence to reject the null hypothesis. The null hypothesis in this context is that there are no differences in mean blood pressure among the three groups. Rejecting the null hypothesis suggests that there is a statistically significant difference in mean blood pressure among at least two of the groups.
