A certain group of test subjects had pulse rates with a mean of 80.9 beats per minute and a standard deviation of 10.7 beats per minute. Use the range rule of thumb to identify the limits separating values that are significantly low or
significantly high. Is a pulse rate of 51.5 beats per minute significantly low or significantly high?
