Random Factors

Question 1

A mail-order company recorded the quarterly turnover (in millions of Rands) over the past four years. The sales data is shown in the table below-

Quarter	Year 1	Year 2	Year 3	Year 4
Jan – Mar	110	112	102	124
Apr – Jun	120	128	140	150
Jul – Sep	192	180	200	206
Aug – Dec	114	162	180	166

Using the ratio to moving average and linear regression, predict the sales volume for each quarter of year 5. assume that cyclical and random factors do not contribute significantly to the time series. Show details of all calculations
