Assume the systolic blood pressure of 30 year old males is normally distributed, with an
average of 122 mmHg and a standard
deviation of 10 mmHg. A random sample of 16
men from this age group is selected. Calculate
the probability that the average blood pressure
of the sample will be greater than 125 mmHg.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
