A study about the blood glucose levels (in mg/dL) of diabetic patients is performed. You wish to test whether there is a significant difference in the blood glucose levels of diabetic patients with good sleep quality and poor sleep quality. By using SPSS, the two-sample t-test is done and the following SPSS outputs are obtained (with some information hidden). Blood Glucose Level Poor Sleep Quality Good Sleep Quality Blood Glucose Level Equal variances assumed Group Statistics Sleep Quality of Patients c) d) e) Equal variances not assumed N 37 31 Mean 121.73 114.97 F Std.

Explain your answer. b) In the hypothesis test, what should be the degree of freedom and the test statistic value under the assumption in (a)? Where, in (i) or (ii), should the test statistic value computed in (b) appear in the SPSS output above? Report the p-value of the test. Write the conclusion in the subject matter. Suppose ₁ and ₂ are the population mean blood glucose levels of diabetic patients with good and poor sleep quality respectively. Find the 95% confidence interval for ₁- H₂. Std Error Difference 1.
