Answer:
a) Let X the random variable that represent the blood pressure for people of a population, and for this case we know the distribution for X is given by:
Where and
b)
And we can find this probability using the complement rule:
And in order to find this probabilities we can use tables for the normal standard distribution, excel or a calculator.
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Part a
Let X the random variable that represent the blood pressure for people of a population, and for this case we know the distribution for X is given by:
Where and
Part b
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule:
And in order to find this probabilities we can use tables for the normal standard distribution, excel or a calculator.
