Consider the recent data on sun spot activity below, available online from the NOAA Space Weather Service. (Sun spots are massive disturbances on the surface of the sun, and they are monitored closely by telecommunication and power companies because their magnetic output disrupts those operations.) \begin{tabular}{|r|r|r|r|} \hline Date & SunSpotCount & Date & SunSpotCount \\ \hline 8/23 & 49 & 9/7 & 110 \\ \hline 8/24 & 69 & 9/8 & 70 \\ \hline 8/25 & 70 & 9/9 & 87 \\ \hline 8/26 & 78 & 9/10 & 62 \\ \hline 8/27 & 85 & 9/11 & 73 \\ \hline 8/28 & 73 & 9/12 & 68 \\ \hline 8/29 & 95 & 9/13 & 44 \\ \hline 8/30 & 118 & 9/14 & 44 \\ \hline 8/31 & 144 & 9/15 & 53 \\ \hline 9/1 & 120 & 9/16 & 77 \\ \hline 9/2 & 108 & 9/17 & 51 \\ \hline 9/3 & 156 & 9/18 & 61 \\ \hline 9/4 & 150 & 9/19 & 62 \\ \hline 9/5 & 105 & 9/20 & 68 \\ \hline 9/6 & 112 & 9/21 & 74 \\ \hline \end{tabular} If you were using a simple 4-day moving average for daily sun spot forecasting, which of these values would be your forecast for September 5th(9/5) ? a. 133.50 b. 129.75 c. 66.25 d. 82.75 e. 76.50
