A personal computer manufacturer is interested in comparing assembly times for two keyboard assembly processes. To do this, the company selects 11 workers at random and asks each of them to use both assembly processes. The assembly time (in minutes) for Process is recorded for each of these workers. Then, the assembly time for Process 2 is recorded for each of the same workers. The data and the differences (Process 1 minus Process 2) are shown in the table below Worker 1 2 3 4 5 6 7 8 10 11 Process 1 61 79 14 69 89 47 31 76 19 67 31 5 2 41 3 5 Process 2 16 16 72 87 36 74 12 62 Difference (Process 1 - Process 2) 27 33 28 2 11 27 2 12 Send data to calculator Assume that the population of these differences in assembly times (Process 1 minus Process 2) is approximately normally distributed Construct a 95% confidence interval for the population mean difference in assembly times for the two processes. Then fra the lower and upper limits of the 95% confidence interval. Carry your intermediate computations to three or more decimal places. Round your answers to two or more decimal places (19 necessary, consulta list of formulas) 5 ? Lower mit Upper limit:
