Use the given data to find the best predicted value of the response variable. Round to two decimal places. Eight pairs of data yield requals0.742 and the regression equation ModifyingAbove y with caret equals 55.8 plus 2.79 x Also, y overbar equals 71.125. What is the best predicted value of y for x equals 2.1? Use a significance level of 0.05. LOADING... Click the icon to view the critical values of the Pearson correlation coefficient r.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

once you solve it out the value of x is 13

answer: 5a, -3a
