Suppose that resting pulse rates among healthy adults are normally distributed with a mean of 73 beats per minute and a standard deviation of 20 beats per minute. Use this table or the ALEKS calculator to find the percentage of healthy adults who have resting pulse rates that are more than 99 beats per minute. For your intermediate computations, use four or more decimal places. Gie your final answer to two decimal places (for example 98.23%).
