A political advisor wants to assess the voter appeal of three candidates, A, B, and C. Twelve voters were asked to watch a 10-minute video speech by each candidate, after which the voters rated each candidate on such factors asappearance, clarity of expression, voice, and overall impression. A final score on a 20-point scale was given to each candidate. Each voter first listened to Candidate A, then Candidate B, then Candidate C.

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…
