ALSO, please be sure to write in the answer em 1.(12 points) An experiment was done to test whether one type of anti-anxiety medication v a greater effect on the number of panic attacks a person with panic disorder had in a an another type of anxiety medication. Specifically, the researchers was interested in month th determining whether there would be a mean difference in panic attacks per month among a) a new anxiety medication called Buspar, b) the standard anti-anxiety medication called Ativan, and c) a ebo. There were three samples of participants, and participants were randomly assigned to one of plac the three test. treatment conditions (Buspar, Ativan, and placebo). Assume an alpha of .05 and a two-tailed Placebo M1 11.3 M2 10.3 n1 = 10 T,-113 Ativan M3-8.5 n3 = 10 T3 85 Buspar n2 10 T2 = 103 SS,-69.20SS2 23.30 SS 45.50 X 3439

Answer 1

Solution:-

30)

SS_between = 40.267

SS_Within = 138

SS_Total = 178.267

31)

DF MS Between Within Total 40.267 138 178.267 2 20.133 275.111 3.939 29

State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.

Null hypothesis: u₁ = u₂ = u₃

Alternative hypothesis: At-least one of the u is not equal.

Formulate an analysis plan. For this analysis, the significance level is 0.05.

Analyze sample data.

F statistics is given by:-

$F=\frac{MSB}{MSE}$

F = 3.939

The P-value = 0.032

Interpret results. Since the P-value (0.032) is less than the significance level (0.05), we have to reject the null hypothesis.

Conclusion:-

Reject H₀, There is sufficient evidence for significant differences between the three effects.
