2. Here is data for a study testing a new anti-anxiety medication. It is predicted that the placebo will have a significant effect compared to no treatment., and the medication will have a larger effect than the placebo. Us alpha = .01. No treatment Placebo Medication Y1 = 12 SS; = 31 n = 11 Y1= 10 Y1 =7 SS; = 25 SS, = 92 %3D %3D n = 11 n; = 11 SSTotal = 301 %3D A. State the hypotheses. B. Make a decision about the null. a. Calculate the ANOVA test. b. Calculate the effect size. C. State conclusion. D. Relate your conclusion to the research. E. If allowed, conduct analytical comparisons. a. State the hypotheses. b. Make a decision about the null. i. Calculate the Fcomp. your ii. Calculate the effect size. 111. State your conclusion.
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.

The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
