1. Think about a 'bread and biscuit factory having skilled, semi-skilled and unskilled manpower. The rate of variation in the annual profits of the skilled manpower is to be compared with the rate of variation in the annual profits of semi-skilled and unskilled manpower. Considering a sample, the mean profits for skilled, semi-skilled and unskilled manpower are Tk.500000, TK.420000, and Tk.330000 with the standard deviations of Tk.19500, Tk.22000, and Tk.22500 respectively. Now make a meaningful comparison with semi-skilled and unskilled manpower for skilled manpower by explaining your findings. 2. Verify time and factor reversal tests for Fisher's index number. 3. The weights (in grams) of packed toothpaste from a production process have been recorded at different time periods of a day and they are 29, 30, 30.1, 30.1, 30, 29.8, and 29.9. Consider the standard margin of weight of each pack is 30 gm. Now comment on the shape of the distributional pattern of the production process. 1.
