a. [18pts] Suppose the data below show the height (in feet) of a sample of Christmas trees grown on a Christmas tree farm, in 2018 and 2019. Do the data provide evidence that the tree heights are systematically taller in all Christmas trees grown on the farm in 2019? Use the 4-step hypothesis testing procedure, with alpha = .05. Describe the p-value picture instead of drawing it.
