Answer:
22.6%, It will provide enough adjustment to suit the chage in work plane
Step-by-step explanation:
Let probability of moving average forecasts, p = 6 months/12 months = 1/2
and probability of not moving average forecasts, q = 1/2
Also, number of months in a year, n = 12
Hence, P(r=6) nCr*p^r*q^n-r = 12C6 *(1/2)^6 *(1/2)^6 where r = months interval
= 12*11*10*9*8*7/6! X (1/64) X (1/64) = 924/4096 = 0.226
Then the percentage of 0.226 is 22.6%
