The weights at birth of five randomly chosen baby Orca whales were 425, 454, 380,
405, and 426 pounds. Assume the distribution of weights is normally distributed. Find
a 95% confidence interval for the mean weight of all baby Orca whales. Report
confidence interval limits to one decimal place.
I need the upper and lower limit
