Recent research indicates that the effectiveness of antidepressant medication is directly related to the severity of the depression (Khan, Brodhead, Kolts & Brown, 2005). Based on pretreatment depression scores, patients were divided into four groups based on their level of depression. After receiving the antidepressant medication, depression scores were measured again and the amount of improvement was recorded for each patient. The following data are similar to the results of the study. Low Moderate High Moderate Moderately Severe Severe 1.2...

7. i) Let n and k be some given positive integers, and x a 1-dimensional NumPy array of length n. Write a Python code that creates the 2-dimensional NumPy array which has k columns all identical to x. You may import numpy as np Perform the test case: ne5 k-3 x = np.arange(0,1,0.2) # the output should be [[. 0. 0.] [0.2 0.2 0.2] [0.4 0.4 0.4) (0.6 0.6 0.6) [0.8 0.8 0.8]] 7. ii) Let a, b, c be...
