An analyst for a large company is examining a new dataset they received in order to estimate a population mean. Suppose that the sample mean of this dataset was equal to 597.3 from 21 datapoints, with a S of 346.2. The analyst wants to create a 95% confidence interval around the sample mean. What is the lower bound of the confidence interval? Round all intermediate and final values to two decimal places. 482.10 394.55 521.75 439.71 363.88
