Process improvement:

Process improvement: A production supervisor wants to know if the variance of chemical yields obtained by using Catalyst 1 differs from that obtained by using Catalyst 2. A sample from each catalyst was drawn and the results are in the next table. Conduct the suitable test and conclude whether there is a difference in the variability of the two catalysts. Date are below. Catlyst1 Catalyst 605 120 845 750 785 712 835 265 695 580 Select one: Q The observed statistic F is .256 and therefore there is no statistical evidence of a difference in the variability of the two processes. 0 The Pvalue is .15 and therefore there is statistical evidence of difference in the variability between the two processes. 0 Observed F is .256 and therefore there is statistical evidence of a difference in the variabilityr of the two processes. 0 The observed F statistic is 2.56 and therefore there is no statistical difference in the variability between the two processes
