Question

a seventh grade student chooses a random sample of 50 out of 400 students. He finds that 7 students have traveled outside the United States. The students claims that over 50 of the students have likely traveled outside the United States. Is the student correct? Explain.

Answer 1

I would say yes. Basically, if I'm doing this right, he picked 50 out of 400 students, and only 7 have been out of the US. So I divided 400 by 50, which equals 8. Then I did 8 times 7, and got 56.
I'm pretty sure that's how you would do that. Hoped this helped!

Answer 2

Yes, the claim of the students that over 50 of the students have likely traveled outside the United States is correct.

Explanation:

Consider the provided information.

It is given that out of 50 students 7 students have traveled outside the United States.

This can be written as:

`(7)/(50)`

Now he claims that over 50 of the students have likely traveled outside the United States.

To find whether he is correct use the formula.

`(Part)/(Sample)=(x)/(Population)`

Substitute the respective value in the above formula as shown:

`(7)/(50)=(x)/(400)`

`(7)/(50)* 400=x`

`x=7* 8`

`x=56`

Here, 56 > 50

Hence, the claim of the students that over 50 of the students have likely traveled outside the United States is correct.
