Suppose the shipping weight of your cheese shop's customized gift baskets is asymmetrically distributed with unknown mean and standard deviation. For a sample of 65 orders, the mean weight is 45 ounces and the standard deviation is 10.2 ounces.

What is the upper bound of the 90 percent confidence interval for the gift basket's average shipping weight?

Note that the correct answer will be evaluated based on the z-values in the summary table in the Teaching Materials section.

Please round your answer to the nearest tenth.

Note that the correct answer will be evaluated based on the full-precision result you would obtain using Excel.
