anvas X 24 Test Statistic p-value (Lower Tail) 0.0699 p-value (Upper Tail) p-value (Two Tail) H&R Block believes the proportion of tax returns submitted to the IRS with errors has increased over the years. So, an auditor for H&R Block randomly selected a sample of 320 tax returns submitted to the IRS from tax year 1995 and 180 tax returns submitted to the IRS from tax year 2005. He classified the returns as "Error" or "No Error" and recorded his findings in Excel. Can H&R Block prove that the difference in the proportion of tax returns submitted to the IRS with errors has decreased over this 10-year period at a=0.05? State the hypothesis in terms of 2005 - 1995. Use the correct excel output above to answer the following question. For the 80% confidence interval for P2005 - P1995, find the upper endpoint.
