The researchers at a large carpet manufacturer have been experimenting with anew dyeing process in hopes of reducing the streakiness that frequently occurs with the current process. As an experiment, 15 carpets are dyed using the new process, and another 15 are dyed using the existing method. Each carpet is rated on a 5-point scale of streakiness, where 5 is Extremely streaky, 4 is Quite streaky, 3 is Somewhat streaky, 2 is A little streaky, and 1 is Not streaky at all. Isthere enough evidence  to infer that the new method is better?
