Can you kindly answer all questions and number each question accordingly. this module is analytical chemistry.
Section A Question 1 35 Marks Consider the following sets of replicate measurements. Replicates A B 1 2.7 3.5 2 3.0 3.1 3 2.0 3.2 4 2.8 3.9 5 2.6 3.1 6 2.8 3.3 7 2.9 3.0 a. C. 1.1 Calculate for each of the data sets (Express your answers with three significant figures): The mean (3 Marks) b. The standard deviation (3 Marks) The 95% confidence interval for each set of data. (6 Marks) 1.2 From the data set A and B, identify the values that can reasonably be suspected as outliers. Prove by statistical mean that the suspected values can be rejected or not at 99% level of confidence (6 Marks) 1.3 Assess separately the precision of the two data sets and conclude. The measurement requirement is 5% of the relative standard deviation. Consider the outcome of question 1.2 when answering this question. (6 Marks) 1.4 Assess the accuracy of the two data sets using the student t-test at 95% confidence level. The true values of these measurements are 2,70 and 3,15 for the data sets A and B respectively. Consider the outcome of question 1.2 when answering this question. 1.5 Demonstrate using the paired t-test from the MS Excel, whether there is a significant difference between the data sets A and B or not. The confidence level of this test is 95%. Consider the outcome of question 1.2 when answering this question. (6 Marks) 1.6 Compare the precision of measurements A and B by using the appropriate statistical test and interpret the result. The confidence level for this test is 95%.
