Answer:

1st, 3rd, and 6th

Step-by-step explanation:

Let's look at each statment...

1.) Correct

Explanation: 10 percent of the students at the school participate in soccer. If 140 is 10% of the number of students at the school, there is more than 140 students at this school.

2.) Incorrect

Explanation: We've already established that the # of students at the school is more than 140.

3.) Correct

Explanation: 10% as a decimal is 0.1 Divide 140 by 0.1 and you get 1,400. So, the total number of students is 1,400.

4.) Incorrect

Explanation: We've already established that the number of students is 1,400, not 290.

5.) Incorrect

Explanation: We've already established that the number of students is 1,400, not 150.

6.) Incorrect

Explanation: If the percent was a ratio, it would be 10:100 or 10/100. This is because a whole percent is 100% and the percent of students who play soccer is 10%.

7.) Correct

Explanation: We've already established that the ratio would be 10:100 or 10/100. Thus, this is correct.

I hope this helps! :)

At a branch office of the company, 350 people are polled and 125 indicate they are in favor of using a corporate American Expres

AlladinOne [14]

Answer:

The P-value is Less than 0.0005%.

Step-by-step explanation:

We are given that at a branch office of the company, 350 people are polled and 125 indicate they are in favor of using a corporate American Express card.

A recent survey at the main corporate headquarters revealed that the 400 employees who responded to the survey indicated that 350 wanted to stay with the American Express Card.

Let $p_1$ = proportion of employees at the headquarters who want the American Express Card.

$p_2$ = proportion of employees at the branch office who want the American Express Card.

So, Null Hypothesis, $H_0$ : $p_1\leq p_2$ {means that the percentage of employees at the headquarters who want the American Express Card is smaller or equal to the percentage of employees at the branch office}

Alternate Hypothesis, $H_A$ : $p_1>p_2$ {means that the percentage of employees at the headquarters who want the American Express Card is greater than the percentage of employees at the branch office}
