- A researcher used a sample of n =16 adults between the ages of 40 and 45. For each person, the researcher recorded the difference between the ratings obtained while smiling and the rating obtained while frowning. On average the cartoons were rated as funnier when the participants were smiling, with an average difference of MD = 1.6, with SS = 135. Are the cartoons rated as significantly funnier when the participants are smiling ? Use a one-tailed test with α = .05. a. The null hypothesis in words is: b. The alternative hypothesis in symbols is: c. The critical t-value is d. The t-statistic is e. Your decision is f. Compute r2 to measure the size of the treatment effect. r2 is g.

A public opinion survey investigated whether a majority (more than 50%) of adults supported a tax increase to help fund the local school system. A random sample of 200 adults showed that 113 of those sampled supported the tax increase. 5G 204 Researchers used these results to test Ho: p = 0.5 versus Ha: p > 0.5, where p is the true proportion of adults that support the tax increase. They calculated a test statistic of z≈ 1.84 and a corresponding P- value of approximately 0.033. Assuming the conditions for inference were met, which of these is an appropriate conclusion?
