The partial pressure of oxygen PaO2 is a measure ofthe amount of oxygen in the blood. Assume that the distribution ofPaO2 levels
Rus_ich [418]

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 \mu=38 mmHg and \sigma= 9 mmHg.

If we take a random sample n= 25 newborns, then  using formula z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}, we have

At x= 36

z=\dfrac{36-38}{\dfrac{9}{\sqrt{25}}}\approx-1.11

At x= 41

z=\dfrac{36-38}{\dfrac{9}{\sqrt{25}}}\approx1.67

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

P(z>-1.11)=1-P(\leq-1.11)=1-(1-P(z\leq1.11))=P(z\leq1.11)=0.8665004\approx0.8665

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

P(-1.11

The Toblerone company packages chocolate candy in a container that is a triangular prism. The base is an
dolphi86 [110]

Answer:

76017.69 mm²

631000 mm³

295045.04 mm³

Step-by-step explanation:

Surface area = bh + 2ls + lb

Since the sides of the triangular prism are equal (equilateral triangle) = 60 mm each

Height = 405 mm

The surface area of triangular = 76017.69 mm

The volume of triangular prism :

1/2 * base * height * length

Volume = 631000 mm³

If amount of chocolate inside = 335954.96 mm3

Empty space =

Volume of triangular prism - amount of chocolate inside

631000 - 335954.96

= 295045.04 mm³
