Association shows that there is a statistical relationship between the two variables in a given data set. The option A,B,D and E are the correct options.
Given information-
The first column has no label with entries 8th grade, 9th grade, total.
The second column is labeled do not use with entries 0. 06, 0. 19, 0. 38.
The third column is labeled use with entries 0. 84, 0. 81, 0. 62.
The fourth column is labeled total with entries 1. 00, 1. 00, 1. 0.
<h3>Association</h3>
Association shows that there is a statistical relationship between the two variables in a given data set.
- A)There is no association between using social media and grade level-The association depends on two or more variable. Thus there is no association between using social media and grade level. Hence this is correct option.
- B)The probability a student uses social media, given that he or she is in 9th grade, is 81%- In the given table it can be conclude that the probability of a 9th grade student using the social media is 81%. Thus this option is the correct option.
- C)A student who is more likely to not use social media is in 8th grade-The probability of not using social media in 8th grade is 6 percent but it is not true that they more likely to not use social media. Thus this is the not correct option.
- D)An 8th grader is more likely to use social media than not- The probability of using the social media for a 8th grade student is more that the not using the social media for a 8th grade student. Thus this is correct option
- E)Knowing a student’s grade level does not help determine if he or she uses social media- It can not be conclude that a student uses or not uses the social media just by knowing his\her grade. Thus this is a correct option.
Hence the option A,B,D and E are the correct options.

Hi there! The answer is 3 multiplied by the square root of 13.
Using the following theorem (Pythagorean Theorem), with a and b representing rectangular sides and c representing the hypotenuse, and the numbers from the picture, we get the following:
Fill in the numbers
Work out the powers
Add up
Take the square root of both sides.
Answer:
YOUR ANSWER IS 9
Step-by-step explanation:
1.80/4= 0.45
2.70/6=0.45
5.40/12=0.45
