For every football game there is a team that is expected to win by a certain number of points. In betting parlance, this is called the spread. If point spreads are accurate, we would expect about half of all games played to result in the favored team winning (beating the spread) and about half of all games to result in the team favored to not beat the spread. The accompanying data represent the results of 45 randomly selected games where a 0 indicates the favored team did not beat the spread and a 1 indicates the favored team beat the spread. Do the data suggest that sport books establish accurate spreads?

Full question attached
Answer and Explanation:
From the question,
Null hypothesis H0=0.5
Alternative hypothesis Ha≠0.5
Given that test statistic z = <p-p/√p(1-p)/n
<p is the sample proportion of favored teams= x/n = 25/45= 0.5556
p is the population proportion =0.50
n= population size/ number of games = 45
Z= 0.5556-0.50/√0.50(1-0.50)/45
= 0.5556-0.50/√0.50(0.50)/45
= 0.75
Two tailed test P-value from table given Z value 0.75
= 0.453
The p value is greater than level of significance 5%, 10% and so we don't reject null hypothesis. Also level of significance is not specified. Therefore option C is correct

Explanation:
He has refused his Assent to Laws, the most wholesome and necessary
for the public good.
1. He has refused to approve necessary colonial laws.
2. He's forbidden the governors to approve necessary colonial laws
and delayed the passing of other laws
He has forbidden his Governors to pass Laws of immediate and pressing
importance, unless suspended in their operation till his Assent should be
obtained; and when so suspended, he has utterly neglected to attend to
them.
3. In some districts he has refused to pass laws unless people gave
up their democratic rights.
He has refused to pass other Laws for the accommodation of large
districts of people, unless those people would relinquish the right of
Representation in the Legislature, a right inestimable to them and
formidable to tyrants only.
4. He has called legislative bodies together hastily and in unusual
places (so that they would give in to his demands).
He has called together legislative bodies at places unusual,
uncomfortable, and distant from the depository of their Public Records,
for the sole purpose of fatiguing them into compliance with his
measures.
He has dissolved Representative Houses repeatedly, for opposing with
manly firmness his invasions on the rights of the people.
5. He has dissolved Legislatures for opposing him when he tried to
take away our rights.
6. After closing down our legislatures, he has refused to let us
elect a new one and our colonies were left unprotected.
He has refused for a long time, after such dissolutions, to cause others
to be elected, whereby the Legislative Powers, incapable of Annihilation,
have returned to the People at large for their exercise; the State
remaining in the mean time exposed to all the dangers of invasion from
without, and convulsions within.
He has endeavoured to prevent the population of these States; for that
purpose obstructing the Laws for Naturalization of Foreigners; refusing
to pass others to encourage their migrations hither, and raising the
conditions of new Appropriations of Lands.
7. He has tried to keep the colonies from growing by preventing
immigration and land ownership by immigrants. (Proclamation of
1763)

How are the conservatory in Canada and the national parks of Canada alike and different? SS6G5
Answers
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The conservatory in Canada and the national parks of Canada are alike because they are two important institutions for Canadian people and they respect and support them because it is an important part of their life.
These are different in that the conservatory of Canda is a music institution that prepares the best musicians of the country, including the Philarmonic Orchestra, and the other, is a government office dedicated to the preservation of the parks and the wildlife in Canada.
Music is an important component of the social life and culture of Canada. Its conservatory is renowned worldwide. On the other hand, the parks of Canada are immense. Most of the Canadian territory is woods, parks, and lakes, full of wildlife. That is why Canadian people support the environment, their parks, and are very proud of them.

How do the three branches share, check, and balance power?
Answers
The system of checks and balances in government was developed to ensure that no one branch of government would become too powerful. The framers of the U.S. Constitution built a system that divides power between the three branches of the U.S. government—legislative, executive and judicial—and includes various limits and controls on the powers of each branch. EX: The president (head of the executive branch) serves as commander in chief of the military forces, but Congress (legislative branch) appropriates funds for the military and votes to declare war. In addition, the Senate must ratify any peace treaties.
