knot ress cor Hi Deaum The molarity of a NaOH solution was determined by titration with KHP. The results of five titrations were 0.1025 M, 0.1087 M, 0.1100 M, 0.1052 M, 0.0997 M. Answer the following questions based on 95% confidence level. d) Calculate the relative standard deviation of the concentration of NaOH. e) Calculate the standard error of the concentration of NaOH. f) Calculate the confidence interval of the concentration of NaOH. Report your answer with appropriate significant figures. g) If the true concentration of this NaOH solution is 0.1045 M, is the sample mean significantly different from the true concentration? h) Another student also measured the concentration of the same NaOH solution. The result of the three titrations were 0.1028 M, 0.1012 M, 0.0983 M. Are the mean concentrations from the two students' result similar to each other? Hint: you need to do a student's t test and a F test.
