29 A sample of difference scores from a repeated-measures experiment has a mean of Mp = 5 with a variance of s² = 64. If the sample size is n = 4, and you had rejected the null hypothesis, which of the following best describes the effect size using estimated d? low O medium O high QUESTION 30 Is there a difference between urban and rural jurisdictions in the hiring of female police officers? In California, for urban jurisdictions (n=77) the mean percentage of female officers is 9.65 (s = 4.17).
