EXAMPLE 10 Summertime is burglary time

An advertisement for a home security system says, “When you go on vacation, burglars go to work. According to FBI statistics, over 26% of home burglaries take place between Memorial Day and Labor Day.”

This is supposed to convince us that burglars are more active in the summer vacation period. Look at your calendar. There are 14 weeks between Memorial Day and Labor Day. As a percentage of the 52 weeks in the year, this is

193

So the ad claims that 26% of burglaries occur in 27% of the year. This seems to make sense, so there is no cause for concern.
