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.
