The partial pressure of oxygen pao2 is a measure ofthe amount of oxygen in the blood. assume that the distribution ofpao2 levels among newborns has a mean of 38 mmhg and astandard deviation of 9 mmhg. if we take a random sample of 25newborns what is the probability that the sample meana) will be greater than 36b) will be between 36 and 41

a) 0.8665

b) 0.8190

Step-by-step explanation:

Given : The partial pressure of oxygen PaO2 is a measure ofthe amount of oxygen in the blood. Assume that the distribution ofPaO2 levels among newborns has a 38 mmHg and 9 mmHg.

If we take a random sample n= 25 newborns, then  using formula , we have

At x= 36

At x= 41

Using table for z-values, the probability that the sample mean will be greater than 36 :

The probability that the sample mean will be between 36 and 41 :-

7.3
