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):

The coach could grade their performance.
Social loafing refers to the fact that a person might not produce much effort when in a group, as opposed when alone. So, these kids know that together they are pretty good, so they don't have to try hard; but when they are alone, they do. In order to prevent this, the coach might want to grade their performance, because then they will try harder.
Answer:
The test result would accept the alternate hypothesis stating that 'More than 10% of the students enrolled in an introductory Chemistry class dropped before the midterm'.
Explanation:
In this case, the null and alternate hypothesis would be:
Null Hypothesis: Less than or equal to 10% of the students enrolled in an introductory Chemistry class dropped before the midterm.
Alternate Hypothesis: More than 10% of the students enrolled in an introductory Chemistry class dropped before the midterm.
A Type I error is when a true null hypothesis is rejected by mistake or due to an error. This means that it is true that 'Less than or equal to 10% of the students enrolled in an introductory Chemistry class dropped before the midterm' but this is rejected due to an error or mistake. Hence, the alternate hypothesis will be found as the result of the test due to the error.
Answer:
The Investiture Controversy between the Holy Roman Emperor and the pope was Option B: who could appoint church officers, the secular emperor or the pope.
Explanation:
During the Middle Ages, the 'Medieval Christian church' was led by Pope and the nation was led by the king. One great disagreement between Pope Gregory VII and King Henry IV (of Holy Roman Emperor) was the question of who would appoint the local church officials. Henry thought that he should have the right to appoint the bishops of the church as he was the king. And Pope opposed stating that he should have this power.
It was not because of how the crusades should be funded or on taxes.
