Question 10 Whlch value is larger, the sample mean for Group A glucose levels or the sample mean for Group B glucose levels? 0 The sample mean for Group B glucose levels 0 Thev are the same. 0 The sample mean for Group A glucose levels USETHE INFORMATION BELOW TO ANSWER QUESTIONS 7THRU 10 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% condence interval for the true mean glucose levels for Group A minus the true mean glucose levels for Group B was computed to be: (711.45, 5.32). Question 7 1 pts Choose the best interpretation for the condence interval in this problem. 0 We are 95% condent that the true rnean glucose levels for Group A Is lowerthan the true rnean glucose levels for Group B. Q We are 95% condent that the true mean glucose levels for Group A is higher than the true Inc-an glucose levels for Gmun B. C) We are 95% condent that there ls no statistically slgnicant dl'erence between the true mean glucose levels for Group A and the true lnean glucose levels for Group B.
