Use the data in the Excel workbook, on the worksheet labeled "Sample," for this question. The first column is just an observation index labeledi to name each observation. The observations are a simple random sample with replacement from a much larger population. The second column contains specific valuesy of a random variableY found in some sampled population. The population standard deviation is not known to you, but it is known thatY has a Normal distribution in the sampled population.

Compute the upper bound of a 99% confidence interval for the population mean of the random variable Y.
