According to the IRS, taxpayers calling the IRS in waited minutes on average for an IRS telephone assister to answer. Do callers who use the IRS help line early in the day have a shorter wait? Suppose a sample of callers who placed their calls to the IRS in the first minutes that the line is open during the day have a mean waiting time of minutes before an IRS telephone assister answers. Based on data from past years, you decide that it is reasonable to assume that the standard deviation of waiting times is minutes. Using these sample results, can you conclude that the waiting time for calls placed during the first minutes the IRS help line is open each day is significantly less than the overall mean waiting time of minutes?
