1. Consider an experiment in which researchers investigate the effects of paper color on examperformance in undergraduate college students. Two exams, one with an easier level of diffi-culty and one with a harder level of difficulty, are prepared for this experiment. For the examof each difficulty level, 10 copies are printed on blue-colored paper and 10 copies are printedon red-colored paper (for a total of 40 printed exams). These exams are randomly distributedto 40 students in an undergraduate psychology course. Below are the sample mean examscores (in points out of 100) for the 10 students in each group represented by a paper colorand exam difficulty.Exam DifficultyEasierHarderBlue84.175.2Paper ColorRed83.464.5a.

Four Quarters the Same as $1? In a study of the “denomination effect,” 43 college students were each given one dollar in the form of four quarters, while 46 other college students were each given one dollar in the form of a dollar bill. All of the students were then given two choices: (1) keep the money; (2) spend the money on gum. The results are given in the accompanying table (based on “The Denomination Effect,” by Priya Raghubir and Joydeep Srivastava, Journal of Consumer Research, Vol. 36.) Use a 0.05 significance level to test the claim that whether students purchased gum or kept the money is independent of whether they were given four quarters or a $1 bill. Is there a “denomination effect”?

Textbook question for practise - A behavioural psychologist has developed a cognitive-behavioural therapy (CBT) technique modified from classic systematic desensitization to reduce her patients’ phobia of spiders. She decides to test the effectiveness of her new therapy approach by selecting ten patients at random to undergo the treatment for 3 months. The patients were asked to rate how much fear they feel/experience when in the presence of a spider/spiders using a scale from 0 (no fear at all) to 100 (extreme panic and fear). They were tested before and after the therapy. The ratings for each patient are as follows: For this question, be sure to do the following: ▪ State the statistical hypotheses (using the appropriate notation). ▪ Indicate whether the research hypothesis is non-directional or directional (and how you know). ▪ Set the decision rules, which will include: o State alpha - 0.05% o Compute the degrees of freedom o Providing the critical value for the test statistic…
