You can do this quickly with StatTools, using the Difference item in the Data Utilities dropdown list, or you can create the differences with Excel formulas. b. Create a times series graph for each CPI component, including the All Items component. Then create a time series graph for each difference variable. Comment on any patterns or trends you see. c. Create a table of correlations between the differences. Comment on any large correlations (or the lack of them). d.

Exact response: Use the associative property to move the parentheses, and the expression becomes (d + 8d) + 1 + 7. Combine like terms, and the expression becomes 9d +8. Use the commutative property to change the order of the terms, and the expression becomes 8 + 9d.
