S D CON Hypothesis test for the difference of population mears: Paired... A computer manufacturer Is Interested in comparing assembly times for two keyboard assembly processes. Process 1 Is an updated process hoped to bring a decrease In assembly time, while Process 2 is the standard process used for several years. Assembly times can vary considerably from worker to worker, and the company decides to eliminate this effect by selecting & workers at random and timing each worker on each assembly process. Half of the workers 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) is recorded, as shown in the table below Worker Process 1 98 54 Process 2 74 55 96 68 52 85 64 Difference -2 -8 -14 -9 - 17 (Process 1 - Process 2) Send data to calculator Based on these data, can the company condude, at the 0.10 level of significance, that the mean assembly time for Process 2 exceeds that of Process 17 Answer this question by performing a hypothesis test regarding Jy (which is ( with a letter "d" subscript), the population mean din In assembly Umes for the two processes. Assume that this population of differences (Process 1 minus Process 2) Is normally distributed- Perform a one talled test. Then complete the parts below. Carry your Intermediate computations to three or more dedmal places and round your answers as spedfled. (IF necessary, consult a list of formulas.) [a) State the null hypothesis Ho and the alternative hypothesis H,- (b] Determine the type of test statistic to use. Type of test statistic: (Choose one) (
