An experiment was conducted to study responses to different methods of taking insulin in patients with type I diabetes. The percentages of glycosolated hemoglobin initially and 3 months after taking insulin by nasal spray are given in the table below.

Patient Number            Before          3 Months After

1                                     12                      10.2           

2                                   7.7                       7.9

3                                     5.9                       6.6

4                                    9.5                     10.4

5                                    7.6                      8.8

6                                     8.6                      9

7                                     11                       9.5

8                                    6.9                     7.7

Conduct a two-sided Wilcoxon Sign Rank Test with alpha = 5% to determine if there is a significant difference in glycosolated hemoglobin after taking insulin by nasal spray. Note: Conduct your subtraction by Before – 3 Months After

38. True or False: There is no significant difference in glycosolated hemoglobin in patients 3 months after taking insulin by nasal spray.

A study was conducted to compare three different methods of administering an intravenous (IV) injection of heparin. Each of the 150 patients in the study received a heparin injection by one of the three methods. For each patient the amount of bruising around the injection site was re corded as “bruising” and “no bruising.” The data were recorded as follows: – Method of Bruising - No Bruising – Injection • A 30 20 - 50 B 10- 40- 50 C...
