Statistics

Part 2 - The president of the company is uncomfortable with the precision of the estimates derived for the sample mean. They are not willing to tolerate a very large error. e = .04, how large would the sample size have to be if they specify a 98% confidence level? Formula: n = [(z-value * sd)/E]^2 Note: n = sample size, z-value will be 2.33 using a z-table to represent the 98% confidence interval, sd = standard deviation, E = 0.04, ^2 means squared, and * means to multiply. Plug known values into the formula and finish the calculation. Round your answer to the next highest whole number. I hope this will help.
