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?

Respuesta :

Answer:

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.

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

  • We are told that the blood pressure of an individual has a z score of 2.1. This means:

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

  • Multiplying this value by 0.98214 by 100

0.98214 x 100 = 98.214%

  • The above calculation means the blood pressure of the person can be found at the 98th percentile.

  • Therefore the blood pressure of this person is said to be Elevated (too high). This poses a health risk to the person.
