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 mu = 4.24 and sigma = 1.05 (Cobb -Clark & Schurer , 2012) , use a two-dailed hypothesis test with alpha = .05 to test the hypothesis that this company's business leaders ' openness to experience is different from the population .

3. Does stress affect the recall ability of police witnesses? This issue was studied in an experiment that tested eyewitness memory a week after a nonstressful interrogation of a cooperative suspect and a stressful interrogation [the way of questioning] of an uncooperative suspect. The numbers of details recalled a week after the incident are summarized in the margin (based on data from "Eyewitness Memory of Police Trainees for Realistic Role Plays," by Yuille et al., Journal of Applied Psychology, Vol. 79, No. 6). Use 0.01 level of significance to test the claim in the article that stress decreased the amount recalled. Assume equal population variances.

McAllister, et al. (2012) compared varsity football and hockey players with varsity athletes from noncontact sports to determine whether exposure to head impacts during one season have an effect on cognitive performance. In the study, tests of new learning performance were significantly poorer for the contact sport athletes compared to the noncontact sport athletes. The following table presents data similar to the results obtained in the study. Noncontact Athletes Contact Athletes 10 7 8 4 7 9 9 3 13 7 7 6 6 10 12 2 Are the neurological test scores significantly lower for the contact athletes than for the noncontact athletes in the control group? Use a one-tailed test with α = .05. Compute the value of r² (percentage of variance accounted for) for these data.

Are nursing salaries in Tampa, Florida, lower than those in Dallas, Texas? Salary data show staff nurses in Tampa earn less than staff nurses in Dallas (The Tampa Tribune, January 15, 2007). Suppose that in a follow-up study of 40 staff nurses in Tampa and 50 staff nurses in Dallas you obtain the following results. Tampa n1 = 40 X1 = $56,100 S1 = $6000 Dallas n2 = 50 X2 = $59,400 S2 = $7000 Complete the confidence interval of the data set
A researcher would like to conduct a study related to student emotional intelligence (EQ) in a university. The researcher would like to examine two objectives in his study. First, he would like to examine whether the EQ training and coaching programme will improve the level of EQ for university students. Second, he would like to study the relationship between student academic performance (CGPA) and students’ emotional intelligence (EQ) in a university. Twenty samples of students from the first year were taken for the study. The researcher has collected the data for a few variables: gender, academic performance, and emotional intelligence (EQ) test score. The study is divided into two parts. First, the student must answer the emotional intelligence (EQ) test assessment before attending the EQ training and coaching programme. Second, the researcher will request the same twenty students to attend a one-month emotional intelligence (EQ) coaching and training programme. Upon completing the…
