The article “Predicting Depressed Patients with Suicidal Ideation from ECG Recordings” (A. Khandoker, V. Luthra, et al., Med Biol Eng Comput, 2017:793–805) reports a study in which systolic blood pressure (in mmHg) was measured for 16 patients suffering from depression and for 29 controls. Those with depression averaged 112.50 with a standard deviation of 13.90, and the controls averaged 110.34 with a standard deviation of 8.65. Can you conclude that the mean systolic blood pressure is higher in those suffering from depression?
