"he object ofa genelal chemistry experiment is to determine the amount {in milliliters} of sodium hydroxide [NaOH) solution needed to neutralize 1 glam of a specied acid. "his will be an exact amount, but when the experiment is run in the laboratory, variation will occur as the result of experimental error. Three titrations are made using phenolphthalein as an indicator of the neutrality of the solution (pH equals 7 fora neutral solution). The three volumes of NaOH required to attain a pH of 7 in each of the three titrations are as follows: 82.07, 75.75, and 75.37 milliliters. Use a 99% condence interval to estimate the mean number of milliliters required to neutralize 1 glam of the acid. [Round your answers to three decimal places.)
