Calculate the percentage annual change in household disposable income for each age group across income quintiles between the last two years in the sample. As in part (a), use the formula for the annual change rather than the logarithm of each of the series. Comment on your calculated numbers. ii. Use a bar chart to plot the annual change in household disposable income by income quintile for households less than 35 years old and 65 years and older between the last two years in the sample. Comment on this figure. c. Obtain the "Household Net Saving" series across all income groups during the sample period. Divide for each income group this series with the sum of the corresponding household disposable income plus the change in pension entitlements. Multiply this ratio by 100 to obtain the saving rate for the specific group. Plot the household saving rate by income quintile and comment on the figure. d. Repeat part (c) for the five age groups instead of the five income groups. e. This part of the question requires you to calculate statistics at the national level (i.e. for Canada as a whole) and the provincial level. The related table that provides data at both levels is located at
