Sociologists published a study on the link between the level of masculinity and criminal behavior in men. Using a sample of newly incarcerated men, the researcher identified 1,170 violent events and 537 events in which violence was avoided that the men were involved in. Each of the sampled men took the Masculinity-Femininity Scale (MFS) test to determine his level of masculinity, based on common male stereotyped traits. MFS scores ranged from 0 to 56 points, with lower scores indicating a more masculine orientation. One goal of the research was to compare the mean MFS scores for two groups of men: those involved in violent events and those who avoided violent events. ..... a. Identify the target parameter for this study. Let µ, = mean MFS score for the violent-event group and u2 = mean MFS score for the avoided-violent-event group. Choose the correct answer below. (01) 2 O A. The target parameter of interest is (02) ² O B. The target parameter of interest is p, - P2. c. The target parameter of interest is µ1 - H2. b. The sample mean MFS score for the violent-event group was 44.51, while the sample mean MFS score for the avoided-violent-event group was 45.06. Is this sufficient information to make the comparison desired by the researcher? Yes No c. In a large-sample test of hypothesis to compare the two means, the test statistic was computed to be z = 1.24. Compute the two-tailed p-value of the test. = (Round to four decimal places as needed.)
