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 :-

Not defective : 25 - 3 = 22
probability of not defective : 22/25
22/25 × 100% = 88%
