The two top questions didn’t count for the rating of a study. If a study scored 0-3 point, it was scored as poor quality. A score of 4-5 points was fair quality, a score of 6-8 points was good quality and eventually if a study had a score of 9-10 points, it was of high quality. Did the study have more than one group

LL Beans Please submit your analysis of this case. In addition, be prepared to discuss your analysis in class. 1. How significant (quantitatively) of a problem is the mismatch between supply and demand for LL Bean? As per the historical series and its associated statistical description (see graph below), we can observe that there is a significant spread between the A/F ratios sine the standard deviation equals 1/3 of the mean. Besides in cases, there is mismatch beyond 50% between the forecast
