An Improved Process Has Been Developed to Increase Yield

question 8

Short Answer

An improved process has been developed to increase yield. Data from the existing process is n = 8, y-bar = 7.6, and s² = 2.1 and the improved process is n = 6, y-bar = 8.0, and s² = 1.5. Is the improved process better at the 0.05 level with a critical value of 1.782.
