Question
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 comma 1751,175
violent events and
538538
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. In a large sample test of hypothesis to compare the two means, the test statistic was computed be z=1.23. Compute the two-tailed p-value of the test. p=????
Explanation / Answer
Two tailed p - value of the test for z = 1.23 will be:
p - value = 2*P(z > 1.23) = 2*0.1093 = 0.2186
