R2 is positive d. for every one-unit increase in x there is a 13.75 unit increase in y e. for every one-unit increase in x there is a 13.75 unit decrease in y 13.75 None of the statements are correct 8 10

Using the data in the image, I need to find the regression using the data analysis in excel. I don’t know which should be the input x or the input y range. Smoking data is to be with each of the remaining four data depicting the types of cancer. Can anyone help?

Annual high temperatures in a certain location have been tracked for several years. Let X represent the year and Y the-high temperature. Based on the data shown below, calculate the regression line (each value to two decimal places). y D 2. 19.44 3. 19.8 4 16.96 16.42 6. 14.78 7 14.94 8. 12.5

Annual high temperatures in a certain location have been tracked for several years. Let XX represent the year and YY the high temperature. Based on the data shown below, calculate the regression line (each value to two decimal places).y =  ___ x + ____ x y 3 11.49 4 10.82 5 11.05 6 13.58 7 13.51 8 17.04 9 18.27 10 19.6

​A set of n = 15 pairs of X and Y scores has SSX = 10, SSY = 40, and SP = 30. What is the slope for the regression equation for predicting Y from X?   a.  ​10/30   b.  ​10/40   c.  ​40/10   d.  ​30/10

Based on the data shown below, calculate the correlation coefficient (to three decimal places). This is the 'r' value you get when you do the regression. x y 2 8.38 3 6.35 4 7.92 5 4.19 6 5.46 7 4.93 8 3.9

The rest of the D is.... c. 107.1 d. Not meaningful
