A plant biologist is interested in studying the height of sunflowers. He measures a large sample of sunflowers and determines that their height is approximately normally distributed with mean 112 cm and standard deviation 16 cm. (a) What is the probability (approximately) that a sunflower will be less than 115 cm tall? Sketch the area corresponding to this probability. (b) What is the probability (approximately) that a sunflower will be between 100 and 120 cm tall?
