According to the IRS, taxpayers calling the IRS in 2017 waited 12 minutes on average for an IRS telephone assister to answer. Do callers who use the IRS help ine early in the day have a shorter wait? Suppose a sample of 50 callers who placed their calis to the 1AS in the first 30 minutes that the line is open during the day have a mean walting time of 10 minutes before an IRS telephone assister answers. Based on data from past years, you decide that it is ressonable to assume that the standard deviation of waiting times is 8 minutes. Using these sample results, can you conclude that the waiting time for cais placed during the first 30 minutes the IRS help line is open each day is significantly less than the overell mean waibing time of 12 minutes? Use a \( =0.05 \). State the hypotheses. \( H_{0} \leq \mu \) \( \boldsymbol{H}_{\approx} \div \mu \) What is the p-value (to 4 decimals)? Can you conclude that calsers who use the 185 help-line eachy in the day have a shorter wak?
