A certain group of test subjects had pulse rates with a mean of
83.9 beats per minute and a standard deviation of 11.6 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 157.1 beats per minute significantly low or
significantly high?
A.) Significantly low values are nothing beats per minute or
lower. (Type an integer or a decimal. Do not round.)
B.) Significantly high values are nothing beats per minute or
higher. (Type an integer or a decimal. Do not round.)
C.) Is a pulse rate of 157.1 beats per minute significantly low
or significantly high?
A. Significantly low, because it is less than two standard
deviations below the mean.
B. Significantly high, because it is greater than two standard
deviations above the mean.
C. Neither, because it is within two standard deviations of the
mean.
D. It is impossible to determine with the information given.
