This statement is true because the survey results show that 58% of managers have caught salespeople cheating on an expense report, and with a 95% confidence interval, the true population proportion falls somewhere between 51.16% and 64.84%. This is true because the 95% confidence interval for the proportion of managers who have caught salespeople cheating on an expense report is calculated as 0.58 +/- 1.96*sqrt(0.58*0.42/200), which gives us a range of 0.5116 to 0.6484, or 51.16% to 64.84%.
