. Redwood trees are the tallest plants on Earth. California is famous for its giant Redwood trees. But just how tall are they? A random sample of 47 California Redwood trees was taken and their heights measured. (This was not easy by the way.) The sample mean average height was 248 feet with a standard deviation of 26 feet. Does this data meet the assumptions necessary to perform a hypothesis test? If so, use a 5% significance level to test the claim that Redwood trees have an average height greater than 240 feet.
