A sample of Blood Pressure measurements (in mmHg) is taken from a patient. The results are as follow:

Sample #	Systolic	Diastolic
1	124	80
2	156	90
3	116	58
4	135	72

a: Find the mean and standard deviation for Systolic and Diastolic measurements. Answer in 2 decimal places.

b:Find the coefficient of variation for Systolic and Diastolic measurements. Answer in 2 decimal places.

c:Which type of blood pressure is more consistent for this patient, based on standard deviation?

d:Which type of blood pressure is more consistent for this patient, based on coefficient of variation?

e:Which measurement (standard deviation or coefficient of variation) is more appropriate for analysis in this situation? Explain Why?
