Strack, martin and Stepper (1988) reported that people rate cartoons as funnier when holding

a pen in their teeth (Which force them to frown.) a researcher attempted to replicate this result using a sample of n = 30 adults between the ages of 32-37. For each person, the researcher recorded the difference between the rating obtained while smiling and the rating obtained while frowning. On the average cartoons were rated as funnier when the participants were smiling, with an average difference of 2.6 with SS = 200.

a) Do the data indicate that the cartoons are rated significantly funnier when the participants are smiling? Use a two tailed test with α = 0.05. (Use the four logical steps in

hypothesis testing)

b) Compute for r2 to measure the size of the treatment effect.

c) Write a sentence describing the outcome of the hypothesis test and the measure of effect

size as it would appear in a research paper.
