Biostats: human blood pressure levels are normally distributed. if you measured an individual's blood pressure and found the blood pressure level to have a z-score of 2.1, what would you conclude about that person?

The z score of a number is the number that shows you the distance of a value from its mean.

Using the z-score table, the probability of z = 2.1 is given as 0.98214.

0.98214 x 100 = 98.214%

Their blood pressure is in the 98th percentile (higher than that of 98% of all people contributing to the distribution)

Step-by-step explanation:

A z-score of 2.1 corresponds to 0.98214 of the area under a normal distribution curve. (You find this by looking in a table of probabilities or by using a suitable calculator.)

Relatively speaking, the person's blood pressure is quite high.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
