Answer:
Her diary gave us information about Siege of Vicksburg.
Explanation:
<u>Emma Balfour is considered to be a celebrated diarist of the Siege of Vicksburg. </u>
In a famous event, she refused to leave and even gave shelter to the soldiers.
She kept a daily diary during her life, recording all the happenings, emotions, sufferings and life during the siege of her city. She wrote about military actions, but also about the everyday lives of the people who tried to survive, about supplies that were lacking, and about fears that they will experience the worst.
Emma survived the siege and her diary today tells us the first-hand testimony of the experience of the Siege of Vicksburg.

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>

<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):



Western Asia, and near the Nile river of northeast Africa.
Answer:
The Framers chose federalism as a way of government because they believed that governmental power inevitably poses a threat to individual liberty, the exercise of governmental power must be restrained, and that to divide governmental power is to prevent its abuse.
