Explanation:
Your question has one part only: <em>a) The average weight of the eggs produced by the young hens is 50.1 grams, and only 25% of their eggs exceed the desired minimum weight. If a Normal model is appropriate, what would the standard deviation of the egg weights be?</em>
<em />
<h2><em>Solution</em></h2><h2><em /></h2>
You are given the <em>mean</em>, the reference value, and the <em>percent of egss that exceeds that minimum</em>.
In terms of the parameters of a normal distribution that is:
- <em>mean</em> =<em> 50.1g</em> (μ)
- Area of the graph above X = 51 g = <em>25%</em>
Using a standard<em> normal distribution</em> table, you can find the Z-score for which the area under the curve is greater than 25%, i.e. 0.25
The tables with two decimals for the Z-score show probability 0.2514 for Z-score of 0.67 and probabilidad 0.2483 for Z-score = 0.68.
Thus, you must interpolate. Since, (0.2514 + 0.2483)/2 ≈ 0.25, your Z-score is in the middle.
That is, Z-score = (0.67 + 0.68)/2 = 0.675.
Now use the formula for Z-score and solve for the <em>standard deviation</em> (σ):
![Z-score=(x-\mu)/\sigma](https://tex.z-dn.net/?f=Z-score%3D%28x-%5Cmu%29%2F%5Csigma)
![0.675=(51g-50.1g)/\sigma](https://tex.z-dn.net/?f=0.675%3D%2851g-50.1g%29%2F%5Csigma)
![\sigma =0.9g/0.675=1.33g](https://tex.z-dn.net/?f=%5Csigma%20%3D0.9g%2F0.675%3D1.33g)

The act is called emancipation. It is a push to get monetary and social rights, political rights or uniformity, regularly for a particularly disappointed gathering, or all the more by and large, in the exchange of such issues. Notwithstanding, comparative ideas might be alluded to by different terms. For example, in the United States, the Civil Rights Movement finished in the Civil Rights Act of 1964.
Answer:
Of the the main causes of air pollution is over population.
Explanation:
In order to sustain more people, we have to produce more food and other things to sustain life. All the manufacturing leads to the burning of fossil fuels.
