In an article in Accounting and Business Research, Beattle and Jones investigate the use and abuse of graphic presentations in the annual reports of United Kingdom firms. The authors found that 65 percent of the sampled companies graph at least one key financial variable, but that 30 percent of the graphics are materially distorted (nonzero vertical axis, exaggerated trend, or the like). Results for U.S. firms have been found to be similar (a) Suppose that in a random sample of 467 graphics from the annual reports of United Kingdom firms, 146 of the graphics are found to be distorted. Find a point estimate of and a 95 percent confidence interval for the proportion of all UK annual report graphics that are distorted. (Round your answers to 4 decimal places.) Point estimate The 95 percent confidence intervalis (b) Based on this interval. can we be 95 percent confident that more than 25 percent of all graphics appearing in the annual reports of UK, firms are distorted? Does this suggest that auditors should understand proper graphing methods? Can we be 05 percent confident that more than 25 percentare distorted? Does this wagest that auditors should understand proper graphing methods? (c) Determine the sample stze needed in order to be 95 percent confident that the sample proportion of UK annual report graphics that are distorted, is when a margin of error of 3 of the population proportion of UK annual report graphics that are distorted. (Round your answer up to the nearest whole number.) The mos
