You have attendance data for for your hot new techno$/$trance themed dance club with the star slider roof and end of night people soaker.

You need to project next week's attendance for security, police and crowd control purposes. Project next week's attendance using three methods:

Three$-$Week moving average; Four$-$Week moving average; and Three$-$Week Weighted $(60/30/10$ w$/$ greatest weight on the most recent week$).$
