The director of the IRS has been flooded with complaints that people must wait more than 55 minutes before seeing an IRS representative. To determine the validity of these complaints, the IRS randomly selects 400 people entering IRS offices across the country and records the times which they must wait before seeing an IRS representative. The average waiting time for the sample is 57 minutes with a standard deviation of 3 minutes. Is there overwhelming evidence to support the claim that the wait time to see an IRS representative is more than 55 minutes at a 0.005 significance level? Step 2 of 3: Is there overwhelming evidence to support the claim that the wait time to see an IRS representative is more than 55 minutes at a 0.005 significance level? State your conclusion in the context of the original problem. Answer Tables Keypad Keyboard Shortcuts Fail to reject the null hypothesis; there is sufficient evidence at the 0.005 level of significance, to conclude that the average wait time to see an IRS representative is more than 55 minutes. Reject the null hypothesis; there is sufficient evidence at the 0.005 level of significance, to conclude that the average wait time to see an IRS representative is more than 55 minutes. Fail to reject the null hypothesis; there is not sufficient evidence at the 0.005 level of significance, to conclude that the average wait time to see an IRS representative is more than 55 minutes.
