An operations manager overseeing an assembly line has had problems with the sequence of jobs. The problem is that bottlenecks occur due to inconsistent sequential operations. He decides to perform an experiment in which two different methods are used to complete the same task: he measures the times (in seconds). The data is listed here. Can he infer that the second method is more consistent than the first method? Perform the appropriate t-test and p-value criterion to answer the question.
