Elizabeth wants to determine the probability that she will be elected student body class president. She surveyed a random sample of 25 students. Based on this data, she has a 36% chance of being elected. Now she wants to determine how accurate this probability may be. Which of the following would be the best method for her to do this?

Question 5 options:

Survey several more random samples of 25 students.

Recheck her math on the first survey for accuracy.

survey several more random samples of any size

Ask the same 25 students she originally surveyed to make sure they are convinced of their choices.

My logical answer is repeat the first survey with different 25 different students

Step-by-step explanation:

The indicates 9 of 25 students surveyed chose her. To determine if her calculation is accurate she needs more survey(s).

How many surveys or the size of sample group could matter.  If she surveys 3 more people, that would not be very accurate.

If she surveys 100 student that would give a better idea of how many students  would vote for her, so I THINK she should repeat the first survey with the same number in the sample size, 25.

Step-by-step explanation:

The parent function is

Now, the transformation rule is

Here, the parent function is scaled vertically by a factor of 7 . Hence, k = 7

Therefore, the equation of the new parabola is
