To estimate the mean sizer of maple trees in a certain area of the Adirondacks a sample of 15 mapple tree heights is collected (Assume population tree heights is normally distributed)38 47 28 42 32 38 34 45 40 24 37 49 38 47 47a. Create a 95% confidence interval for the population mean of maple tree heights.b. create a 99% confidence interval for the population mean of maple tree heights c. What sample size would you need to estimate the population average heights of the maple trees with an error of 0.2 feet at 95% confidence (assume population standard deviation is 8.4 ft.)
