You plan to build a Confidence Interval to estimate the mean of a population for which the standard deviation is known to be 10.7. Find the minimum sample size needed to guarantee with 90% probability that your estimate is within Margin of Error 1.1 of the true population mean. Keep at least 4 decimal places in Zc to avoid rounding errors. Enter a whole number. Submit Question
