A new post-surgical treatment is being compared with a standard treatment. Seven subjects receive the new treatment, while seven others (the controls) receive the standard treatment. The recovery times, in days, are given below. Treatment: 12 13 15 19 20 21 22.00 Control: 18 23 24 30 32 35 39 Let μx represent the population mean for the control patients and let μy represent the population mean for the treated patients. Find a 98% confidence interval for the difference μx - My. (Round the final answers to three decimal places.)
