NT16. It appears that there is some truth to the old adage"That which doesn't kill us makes us stronger." Seery,Holman, and Silver (2010) found that individuals withsome history of adversity report better mental healthand higher well-being compared to people with littleor no history of adversity. In an attempt to examinethis phenomenon, a researcher surveys a group of col-lege students to determine the negative life events thatthey experienced in the past 5 years and their currentfeeling of well-being. For n = 18 participants with 2or fewer negative experiences, the average well-beingscore is M = 42 with SS = 398, and for n =ticipants with 5 to 10 negative experiences the averagescore is M = 48.6 with SS = 370.a. Is there a significant difference between the twopopulations represented by these two samples?Use a two-tailed test with a = .01.16 par-%3D%3D%3D%3Db.

Machiavellian describes negative character traits that include manipulation, cunning, duplicity, deception, and bad faith. A questionnaire by email was administered to a random sample of 700 accounting alumni of a large southwestern university; however, due to nonresponse and incomplete answers, only 198 questionnaires could be analyzed. Several variables were measured, including age, gender, level of education, income, job satisfaction score, and Machiavellian (“Mach") rating score.

5. In the United States, there is a strong relationship between education and smoking: well-educated people are less likely to smoke. Does a similar relationship hold in France? To find out, researchers recorded the level of education and smoking status of a random sample of 459 French men aged 20 to 60 years.36 The two-way table below displays the data. Is there convincing evidence of an association between smoking status and educational level among French men aged 20 to 60 years?

The personality characteristics of business leaders (e.g., CEOS) are related to the operations of the businesses that they lead (Oreg & Berson, 2018). Traits like openness to experience are related to positive financial outcomes and other traits are related to negative financial outcomes for their businesses. Suppose that a board of directors is interested in evaluating the personality of their leadership. Among a sample of n = 16 managers, the sample mean of the openness to experiences dimension of personality was M = 4.50. Assuming that u = 4.24 and o = 1.05 (Cobb-Clark & Schurer, 2012), use a two-tailed hypothesis test with a = .05 to test the hypothesis that this company's business leaders' openness to experience is different from the population.
