Extracted text: Assume that an adult female is randomly selected. Suppose females have pulse rates that are normally distributed with a mean of 72.0 beats per minute and a standard deviation of 12.5 beats per minute. Find the probability of a pulse rate between 56 beats per minute and 68 beats per minute. (Hint: Draw a graph.) The probability is
