The price of a head of iceberg lettuce varies greatly with the season and the geographic location of a store. During February, a researcher contacts a random sample of 39 grocery stores across Canada and asks the produce manager of each to state the current price charged for a head of iceberg lettuce. Using the researcher's results that follow, construct a 99% confidence interval to estimate the mean price of a head of iceberg lettuce in February in Canada.

![The price of a head of iceberg lettuce varies greatly with the season and the geographic location of a store. During February, a researcher contacts a random sample of 39 grocery stores across Canada and asks the produce manager of each to state the current price charged for a head of iceberg lettuce. Using the researcher’s results that follow, construct a 99% confidence interval to estimate the mean price of a head of iceberg lettuce in February in Canada. Assume that σ is 0.205.
