A 0.1475-M solution of Ba(OH)2 was used to titrate the acetic acid (60.05 g/mol) in a dilute aqueous solution. The following results were obtained. (See attached image) (a) Calculate the mean w/v percentage of acetic acid in the sample. (b) Calculate the standard deviation for the results. (Take note if n-1 should be used) (c) Calculate the 90% confidence interval for the mean. (d) (d) At the 90% confidence level, could any of the results be discarded?
