explain further. Step 4: Interpret the Results We compare the calculated z-score to the critical z-score for a two-tailed test at the 0.05 significance level, which is 1.96. Since -1.21 is not less than -1.96 or greater than 1.96, we do not reject the null hypothesis. Step 5: Draw a Conclusion Since we did not reject the null hypothesis, we conclude that based on this sample, we do not have enough evidence to say that the recidivism rate for felons who completed the employment program is significantly different from the overall recidivism rate in the state
