After treatment, the sample mean is found to be M 55. a) If the sample variance is s-32, use a two-tailed test with ?-0.05 to determine whether the treatment effect is significant and compute Cohen's d b) If the sample variance is s- 72, repeat the test and...

Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...
