Question

An article in the Transactions of the Institution of Chemical Engineers (Vol. 34, 1956, pp. 280–293) reported data from an experiment investigating the effect of several process variables on the vapor phase oxidation of naphthalene. A sample of the percentage mole conversion of naphthalene to maleic anhydride follows: 4.2, 4.7, 4.7, 5.0, 3.8, 3.6, 3.0, 5.1, 3.1, 3.8, 4.8, 4.0, 5.2, 4.3, 2.8, 2.0, 2.8, 3.3, 4.8, and 5.0.

(a) Calculate the sample mean. Complete using excel and please include steps.

(b) Calculate the sample variance and sample standard deviation. Complete using excel and please include steps.

(c) Construct a box plot of the data, first by hand and include all equations and calculations for all required quantities and second by using EXCEL. Please include steps for excel part. Thank you.
