Refer to Exercise 14.11. Suppose the output quantities in 1970, measured in billions of units purchased, are as follows:

Durable goods: 10.9
Nondurable goods: 14.02
Services: 42.6
a. Use the outputs to calculate the Laspeyres index from 1960 to 2015 (same increments as in Exercise 14.11) with 1970 as the base period.
b. Plot the simple composite index of Exercise 14.11 and the Laspeyres index of part a on the same graph. Comment on the differences between the two indexes.
