DETAILS ILLOWSKYINTROSTAT1 8.1.018.PR. 4. [-/7 Points] A sample of 20 heads of lettuce was selected. Assume that the population distribution of head weight is normal. The weight of each head of lettuce was then recorded. The mean weight was 2.2 pounds with a standard deviation of 0.1 pounds. The population standard deviation is known to be 0.2 pounds. Construct a 95% confidence interval for the population mean weight of the heads of lettuce. State the confidence interval. (Round your answers to two decimal places.) Sketch the graph.
