Problem 2 You’re looking into two manufacturers (A and B) from which to purchase a large number of paving slabs for a large-scale construction project. You may use one manufacturer as a backup if necessary, but only if there’s no significant difference in the weights of their paving slabs. Formulate and draw conclusions with ?? = 0.01 about a set of hypotheses using a nonparametric test. Use the data in attached.
