(8 points) The acidity or alkalinity of a solution is measured using pH.ApH less than 7 is acidic; a pH greater than 7 is alkaline. The following data represent the pH in samples of bottled water (top two rows) and tap water (bottom two rows). Source, Emily McCarney, student at Joliet Junior College a. Determine the mean and median pH for each type of water. Comment on the differences between the two water types. b. Suppose the pH of 7.10 in tap water was incorrectly recorded as 1.70. What are the mean and median pH as the result? How does the error affect the mean? the median? What property of the median does this illustrate
