Answer: 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 :-
3 x $37.25 = $111.75
$229.25 - $111.75 = $117.50
$117.50 ÷ 5 = $23.50
So the answer is B
31. +
34. -
To figure out more, just solve the known problem, and then go over what the answer would be to the unknown one until you find the answer that makes it true.
Answer:
First number --> x
Second number --> y
x + y = 14 --> x = 14 - y
x - y = 4
so
14 - y - y = 4
14 - 2y = 4
2y = 10
y = 5
so
x = 14 -5
x = 9
