12. A certain group of test subjects had pulse rates with a mean of 84.484.4 beats per minute and a standard deviation of 11.211.2 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 56.856.8 beats per minute significantly low or significantly high? Significantly low values are nothing beats per minute or lower. (Type an integer or a decimal. Do not round.) 14....
