A study was conducted to investigate the effectiveness of hypnotism in reducing pain. Results for 8 randomly selected subjects are shown in the data below.Subject: A, B, C, D, E, F, G, HBefore: 6.6, 6.5, 9.0, 10.3, 11.3, 8.1, 6.3, 11.6After: 6.8, 2.4, 7.4, 8.5, 8.1, 6.1, 3.4, 2.0A lower score indicates less pain. The "before" value is matched toan "after" value and the differences are calculated. The differences have a normal distribution. Are the sensory measurements, on average, lower after hypnotism?Test at a 5% significance level.

A report included data from a study in which 789 people in a representative sample of college students age 18 to 24 were asked how they perceive their money management skills. Possible responses were excellent, good, average, not very good, and poor. Each student in the sample was also classified by sex, resulting in the data in the table. Perception of Money Management Skills Not Very Good Excellent Good Average Poor Male 102 138 88 17 8 Female 81 193 136 22 4 Is there convincing evidence that there is an association between sex and how students perceive their money management skills? Test the relevant hypotheses using a significance level of a = 0.05. State the appropriate null and alternative hypotheses. O Ho: The proportions falling into each of the four perceptions of money management skills are the same for both sexes. H: The proportions falling into each of the four perceptions of money management skills are not the same for both sexes. O Ho: There is an association between sex…
What age groups use social networking sites? A recent study produced the following data about 768 individuals who were asked their age and which of three social networking sites they used most often. (People who did not use such sites were excluded from the study).

Give your answer in reduced (simplified) fraction. (Example: 1/2) Find the probability that the selected subject preferred Twitter, given that he or she was in the 45 – 64 age group.
Suppose that you wanted to design an investigation that examined the association between energy drink consumption and social interaction. You select your sample population and begin making your observations. As the research progresses, you suspect that a number of the subjects exhibit behavioral changes simply related to their knowledge of being enrolled in the study and the increased attention they are receiving as subjects. This phenomenon is known as: Group of answer choices selection bias the Hawthorne effect healthy participant effect misclassification error the Rosenthal effect
