[Questiоn A] Yоur mаnаger hаs asked yоu to review the following writeup. “We are looking at chemical yield data from the past four years over our assembly lines. We’ve noted conditions of temperature, purity, and the source manufacturer. We just happened to find these old production logs, and they were fantastic sources of data. We’re seeing some distinct patterns in terms of temperature and purity effects on the yield, and it also looks like the source manufacturer makes a difference. Our yield is currently about 65%, and we want to bump it up to 70%. From the analyses we’ve run on this past data, it looks like temperature needs to be held at a certain level, and the purity of main ingredients cannot go below 92%. Manufacturers A and B are fine, but C isn’t working. I propose we put into effect immediately policies which will adjust temperature, purity, and source manufacturer to ensure quality yields.” In your opinion, based on what you have learned about statistical analysis in this class, what is your response? Please write 1-2 paragraphs outlining whether you agree and what your rationale is.
