Pepe Delgados is looking to redesign its kitchen layout with two goals in mind: (i) reducing the average time it takes to produce a chile relleno, and (ii) reducing the variability in the time it takes to produce a chile relleno. You have two candidate designs (A and B), and you implement each design for one week, collecting samples for each. Your sample data for production times are below. Chile relleno samples Mean Standard deviation Layout A 25 12.33 1.93 Layout B 21 13.94 4.39
