Syringes, pens, jet injectors, pumps, ports and even inhalers are the various ways for diabetics to take insulin. Currently most diabetics take insulin using syringes or pens. A research study was completed to compare the effectiveness of these two different methods of delivering insulin to diabetics. Two independent random samples of 100 diabetics comprising Group A (using syringes) and 100 diabetics comprising Group B (using pens). Both groups were carefully monitored and their glucose levels measured in mg/dl (milligrams per deciliter) two hours after injections. Their glucose levels were compared and a 95% confidence interval for the true mean glucose levels for Group A minus the true mean glucose levels for Group B was computed to be: (–11.45, 5.32). This problem deals with which of the following? Two proportions One Proportion Two means One mean
