According to law enforcement records, the proportion of all drivers who have received at least one speeding ticket is 0.20. Let’s say we choose a large random sample of drivers and determine the proportion who have received at least one speeding ticket. We know, if the sampling method is repeated, that the sample proportion will vary from sample to sample. In fact, if we look at the sampling distribution in this case, we will see a distribution that is Normal in shape, with a mean (or center) of 0.20 and a standard deviation of 0.024. From this information, we know the middle 68% of this distribution will be between approximately what two values?
