Problem 2 A factory manager wishes to know whether the efficiency of employees working in a high-noise area could be improved by reducing the noise level. The following table gives efficiency rating taken before and after noise-reduction measures were introduced for 15 affected employees. Can we conclude from these data, at the 0.01 level of significance, the reducing the noise level raises the efficiency level of employees? A higher number indicates a higher efficiency.
