with doing a t-test? The significance values obtained by the explore procedure are less than 1. The value is not normally distributed because the value is less than .1. The results across the two variables are similar so a T-test can be done. The mean is close for both of the socioeconomic indexes and is located in the descriptive box.

Compare the mean baseline and posttest depression scores of the experimental group. Was this an expected finding? Provide a rationale for your answer. The data shows that there was an improvement in the mean baseline and posttest depression scores of the experimental group. The baseline mean depression score was 14.00‚ while the post-test

and qualitative tools‚ what evidence is there that quality is getting better? Pod Weight control According to Pod Weight control chart in Appendix‚ the pod weight performance variability is within the control limit (between 2.774 - 2.835)‚ which means the process is in control. This indicates the quality is getting better since the Pod Weight defect rate is normal (Pod Weight measurement is a part of defect report issued by operator‚ which continue 1% after Greenlight implementation) and in control
