. What is the best predicted value ofyfor x=3.7
The answer key says 12.75, but Im not sure why? I believe it
is y = 3(4.3) which is 12.9. Unless the key is wrong? Thank
you.
29) Use the given data to find the best predicted value of the response variable. 29) Four pairs of data yield r = 0.942 and the regression equation y = 3x. Also, y = 12.75. What is the best predicted value of y for x = 4.3?

Six pairs of data yield r = 0.444 and the regression equation y hat = 5x + 2. Also, y bar = 18.3. What is the best predicted value of y for x = 5?
Use the given data to find the best predicted value of the response variable. Eight pairs of data yield r = 0.708 and the regression equation y = 55.8 + 2.79x. Also y = 71.125. What is the best predicted value of y for x = 5.7?
The regression equation relating dexterity scores (x) and productivity scores (y) for the employees of a company is y = 5.50 + 1.91x. Ten pairs of data were used to obtain the equation. The sample data yield r = 0.986 and y = 56.3. What is the best predicted productivity score for a person whose dexterity score is 39? 799.9 80 O - 79.99 79.99
Question 11 (8 points) Find the best predicted value of y corresponding to the given value of x. A Eight pairs of data yield r=0.708 and the regression equation y = 55.8 + 2.79%. Also, y = 71.125. What is the best predicted value of y for x = 9.1? 1) 510.57 2) 57.80 3) 71.13 4) 81.19

Please help. Show work so I can understand how to do it
Ten pairs of data yield r = 0.003 and the regression equation =2+3x Also, the mean = 5 What is the best predicted value of y for x = 2? 7.0 5.0 8.0 17.0
please provide a detailed answer, thank you!
Assume that the given x-value comes from within the range of sample data. (In other words, there will be no extrapolation.) Round your answers to 3 places after the decimal point, if necessary. (a) Suppose a sample of 16 pairs of sample data result in a test statistic of r = 0.724 and the regression equation 0 = 2.4 - 8.9. Additionally, y = 43.1 for this data. What is the best predicted...
