I'm impressed you went to the effort of pasting in your homework question for others to answer for you.

polyfit_demo.m

For #1, use data = xlsread(filename).

For 2 and 3, I don't know the difference between normalization of "decimal" method and "min-max" method. You might find the function mat2gray() helpful. It scales the min to 0, the max to 1, and linearly scales everything in between.

For #4, you can use conv(signal, kernel, 'same') where kernel is a vector of 1's that cover the 5 month range divided by the number of elements in that vector.

I don't know how to do the forecasting 3 months into the future. Perhaps you just need to use polyfit() to fit the last 5 months to a polynomial and then extrapolate out to 3 months from now. I'm attaching a polyfit demo.
