How many kinds of business did the alteration affect?
The alteration affected kinds of business accounting for 60 percent of total retail sales for September and 9 percent for October. Note that the percent value changed for September because the t-statistics for September changed for two reasons. First, the data were revised to include results from the larger monthly retail trade survey sample. Second, new information from the October 2001 levels changes the range of typical levels for September.
