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 :-

$P(-1.11$

Travis is cutting strips of paper for a project. He needs strips that are 114 inches wide. He cut his first strip too wide. His

choli [55]

Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

The length Travis needs to cut = 114 inches

Percent of error = 10%

Let's assume he cuts x inches wide strip

So from the percent of error formula:

$\rm \dfrac{x-114}{114} = \dfrac{10}{100}$

$\rm x = \dfrac{114}{10}+114$

$\rm x = \dfrac{1254}{10}\Rightarrow \dfrac {627}{5}$ or

$\rm x = 125\dfrac{2}{5} \ inches$

Thus, Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches
