The data from two random samples of 100 students regarding what pet they own is given below.
Dog Cat Bird Total
Sample 1 54 38 8 100
Sample 2 39 49 12 100
Based on the two samples, what percentage of students own a bird as a pet?
(1 point)
The percentage of students who own a bird as a pet in Sample 1 is 8%, and in Sample 2 is 12%. Therefore, combining the two samples, the percentage of students who own a bird as a pet is (8+12)/2 = 10%.
Answer: 10%
To ensure the peaceful development of nations. . . the United States has taken a leading part in establishing the United Nations, The United Nations is designed to make possible lasting freedom and independence for all its members. We shall not realize our objectives, however, unless we are willing to help free peoples to maintain their free institutions and their national integrity against aggressive movements that seek to impose upon them totalitarian regimes. . . . totalitarian regimes . . . undermine the foundations of international peace and hence the security of the United States.
The peoples of a number of countries of the world have recently had totalitarian regimes forced upon them against their will. The Government of the United States has made frequent protests against coercion and intimidation, in violation of the Yalta agreement, in Poland, Rumania, and Bulgaria. I must also state that in a number of other countries there have been similar developments.
At the present moment in world history nearly every nation must choose between alternative ways of life. The choice is too often not a free one.
One way of life is based upon the will of the majority, and is distinguished by free institutions, representative government, free elections, guarantees of individual liberty, freedom of speech and religion, and freedom from political oppression.
The second way of life is based upon the will of a minority forcibly imposed upon the majority. It relies upon terror and oppression, a controlled press and radio; fixed elections, and the suppression of personal freedoms.
I believe that it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures.
Use the excerpt to answer the question.
The excerpt illustrates which of the following post-WWII situations? EXPLAIN
A. the reason behind the formation of the United Nations
B. the importance of American financial support to the Middle East
C. the emergence of self-determination as an ideal for nations after the war
D. the rise of the United States and the Soviet Union as competing superpowers
C. The excerpt illustrates the emergence of self-determination as an ideal for nations after the war. The passage emphasizes the importance of free institutions, representative government, and individual liberties, while condemning totalitarian regimes that impose their will on the majority. The United States pledges to support free peoples who resist subjugation, reflecting a commitment to self-determination. This ideal was a driving force behind the formation of the United Nations, but the excerpt focuses specifically on the importance of free choice and resistance to oppression. The passage does not directly address American financial support to the Middle East or the rise of the United States and the Soviet Union as competing superpowers.
To find the percentage of students who own a bird as a pet, we need to compare the number of students who own a bird to the total number of students in both samples.
First, let's calculate the number of students who own a bird in each sample:
- In Sample 1, 8 students own a bird.
- In Sample 2, 12 students own a bird.
Next, let's find the total number of students who own a bird:
- Total number of students who own a bird = Number of students who own a bird in Sample 1 + Number of students who own a bird in Sample 2
- Total number of students who own a bird = 8 + 12 = 20
Now, let's calculate the percentage of students who own a bird:
- Percentage of students who own a bird = (Total number of students who own a bird / Total number of students) * 100
- Percentage of students who own a bird = (20 / 200) * 100 = 10%
Therefore, based on the two samples, 10% of students own a bird as a pet.
