However, more data sets are needed to draw definitive <br />conclusions. <br />Comparison of the Current Duai Stream Bi-Weekly Method to the Dual Stream Weekly <br />Method <br />The upper and lower confidence interva�s of the weekly dual stream collection routes were not <br />significantly different ihan the bi-weckly dual stream (control) routes. Thus, the materials <br />composztion is projected to remain similar. <br />It appeazs on a monihly basis that greater quantities of materials aze likely to be collected with <br />weekly collection as compared to bi-weekly collection. However, more data sets arc needed to <br />draw defznitive conclnsions. <br />Comparison of the Current Dual Stream Bi-Weekiy Method io the Dual Stream Bi- <br />Weekly Method with Additional Ed�cation <br />The upper anc� Iower confidence intervals of thc bi-weekl.y, dual stream with additaonal <br />education colIection routes were not significantly different than the bi-weekly dual stzeam <br />{control) �outes. Thus, the naaterials composition is projected to remain similar. <br />It appears that additional data sets are needed to draw any definitive conclusions as it relates to <br />quantities set out for collection using ihe two approaches. <br />01-00253-1410i-Q101 � 070001 � 13560 P:113500 Ramsey Co. 20U31RTA1RosevillelFA1B1544- Fina] Data Analysis <br />
