The acidity or alkalinity of a solution is measured using pH

The acidity or alkalinity of a solution is measured using pH. A pH less than 7 is acidic; a pH greater than 7 is alkaline. The accompanying data represent the pH in samples of bottled water and tap water Complete parts (a) and (b) Compute the mean median and mode pH for each type of water in table (a) only. F or tap water. the mean pH is .(Round to the nearest thousandth as needed.)

Solution

Mean =7.52083

Ascending order:

7.10,7.45,7.45,7.47,7.47,7.47,7.50,7.52,7.56,7.65,7.68,7.93

Mean = (7.47+7.5)/2 = 7.484999999999999

Mode = 7.47

For bottled:

Mean = 5.175

Ascending Order:

4.78,5.09,5.13,5.15,5.20,5.22,5.23,5.24,5.26,5.26,5.26,5.28

Median =(5.22+5.23)/2 = 5.225

Mode:5.26
