Maximum Contaminant Levels (MCLs) are regulations on water quality set by the United States Environmental Protection Agency. Researchers measured the Chloramines MCLs (in mg/L) of water samples from random locations of each of two wells. The data are given below. Sample sizeSample meanSample sdWell A153.7 0.3Well B193.40.6Assume normal populations with equal variance and construct a 95% confidence interval for the difference in mean MCLs levels. Find the upper bound of the confidence interval (round off to second decimal place).
