limits separating values that are significantly low or significantly high. Is a pulse rate of 116.4 beats per minute significantly low or significantly high?
Significantly low values are 61.2 beats per minute or lower. (Type an integer or a decimal. Do not round.)
Significantly high values are 106.4 beats per minute or higher. (Type an integer or a decimal. Do not round.)
Is a pulse rate of 116.4 beats per minute significantly low or significantly high?
A. Significantly high, because it is more than two standard deviations above the mean.
B. Neither, because it is within two standard deviations of the mean
C. Significantly low, because it is more than two standard deviations below the mean.
D. It is impossible to determine with the information given.
Answer
\(\boxed{\text{The pulse rate of 116.4 beats per minute is significantly high.}}\)
Step 1 ：Given that the pulse rate is 116.4 beats per minute.
Step 2 ：We are also given that significantly high values are 106.4 beats per minute or higher.
Step 3 ：Comparing the given pulse rate with the limit for significantly high values, we find that 116.4 is greater than 106.4.
Step 4 ：\(116.4 > 106.4\)
Step 5 ：Therefore, the pulse rate of 116.4 beats per minute is significantly high.
Step 6 ：\(\boxed{\text{The pulse rate of 116.4 beats per minute is significantly high.}}\)
