The weights at the 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 weigh of all baby orca whales. Give the confidence interval in the form "estimate t margin of error." Round to the nearest tenth of a pound. (a) Provide detailed calculations; use technology to calculate required sample statistics and percentiles. (b) Verify your results using technology (provide the output).
