In the kidney cooling data of DB15, the baseline (time 0) means are ml =

34.40 for saline infusion and m2 = 36.12 for ice slush, each based on 12 readings. (Use two decimal places throughout for easier calculation.) The respective estimated standard deviations are sl - 3.25 and s2 - 1.17.

Find 95 % confidence intervals on the means for each treatment. Are they similar?
