CetaceaNow is a conservationist organization that monitors the health of whale and dolphin populations worldwide. As part of their work, they are modelling the lengths of killer whale calves that will be born over the next decade. For their model, CetaceaNow is using a normal distribution with a mean of 280 cm and a standard deviation of 20 cm. Use this table or the ALEKS calculator to find the percentage of killer whale calves with a length of between 269 cm and 299 cm according to the model. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%).
