The number of girls who attend a summer basketball camp has

The number of girls who attend a summer basketball camp has been recorded for the seven years the camp has been offered. Use exponential smoothing with a smoothing constant of .8 to forecast attendance for the eighth year. 75, 78, 75, 120, 118, 113, 146

Solution

for forcasting the 8 with a = 0.8 we will do this

(118*0.8 + 113*0.8 + 146*0.8 )/(118+113+146)*100 = 79.94 = 80

hence the answer will be 80
