Answer:
And since we need to use excel the code in order to find the answer would be:
=NORM.DIST(55,50,5,TRUE)-NORM.DIST(40,50,5,TRUE)
And the answer would be:
Explanation:
Let X the random variable that represent the respiratory rate of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And since we need to use excel the code in order to find the answer would be:
=NORM.DIST(55,50,5,TRUE)-NORM.DIST(40,50,5,TRUE)
And the answer would be:
