A computer manufacturer is interested in comparing assembly times for two keyboard assembly processes. Assembly times can vary considerably from workerto worker, and the company decides to eliminate this effect by selecting 10 workers at random and timing each worker on each assembly process. Half of theworkers are chosen at random to use Process 1 first, and the rest use Process 2 first. For each worker and each process, the assembly time (in minutes) isrecorded, as shown in the table below.Worker1256.710Process 151425661328567567879Process 243476451357953425587Difference8(Process 1 - Process 2)-5-810-36.141423-8Send data to calculatorBased on these data, can the company conclude, at the 0.05 level of significance, that the mean assembly times for the two processes differ? Answer thisquestion by performing a hypothesis test regarding u, (which is u with a letter "d" subscript), the population mean difference in assembly times for the twoprocesses. Assume that this population of differences (Process 1 minus Process 2) is normally distributed.Perform a two-tailed test. Then complete the parts below.
