A certain group of test subjects had pulse rates with a mean of 78.9 beats per minute and a standard deviation of 11.7 beats per minute. Use the range rule of thumb for identifying
significant values to identify the limits separating values that are significantly low or significantly high. Is a pulse rate of 92.3 beats per minute significantly low or significantly high?
Significantly low values are beats per minute or lower

Is a pulse rate of 92.3 beats per minute significantly low or significantly high?
beats per minute or higher.
OA. Significantly low, because it is more than two standard deviations below the mean
OB. Neither, because it is within two standard deviations of the mean
OC. Significantly high, because it is more than two standard deviations above the mean
