Unformatted text preview: Analysis for glossy types For both flat and glossy types of cellophane the relationship between leadtime and width of rolls ordered is fairly strong and positive. This is illustrated by the reasonably tight scatter of regression line fitted to the scatterplots and the positive slope of the lines. The r 2 values for flat and glossy are respectively .5943 and .6331 respectively, yielding corresponding correlations of 0.771 and .796. We interpret the r 2 values for flat and glossy as follows: flat 77.1% of the sample variation in leadtimes is explained by width of the rolls ordered; glossy 79.6% of the sample variation in leadtimes is explained by width of the rolls ordered. These interpretations are consistent with those illustrated by the scatterplots....
