[Objective: Find a Confidence Interval for Sample Mean] the Weights

question 9

Multiple Choice

[Objective: Find a confidence interval for sample mean] 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. Use technology for your calculations. Give the confidence interval in the form "estimate margin of error". Round to the nearest tenth of a pound.
