A year ago, the Department of Transportation (DOT) for a highly populated state released a series of Public Service Announcements (PSAs) to help combat aggressive driving. Shortly after the release of the PSAs, 46% of the drivers in the state reported they had changed their driving habits after watching the PSAs. Now that the PSAs have been running for a year, if the proportion of drivers who changed their driving habits has increased since the initial release, the DOT will stop airing the PSAs. The DOT takes a new random sample of 233 drivers in the state and finds that 125 of them report changing their driving habits after watching the PSAs.
