Question

next, stem and leaf collected data on the amount of the compound added to each bag (in grams), x, and the weekly growth of the sunflowers treated with each bag (in centimeters), y. the least squares regression line of this data set is: y = 0.278x - 14.229 how much growth does this line predict if stem and leaf agriculture uses fertilizer from a bag that has 172 grams of the compound? round your answer to the nearest thousandth. centimeters

Explanation:

Step1: Identify the regression equation and the value of x

The regression line is \( y = 0.278x - 14.229 \), and we need to find the predicted growth when \( x = 172 \) (grams of the compound).

Step2: Substitute x into the regression equation

Substitute \( x = 172 \) into \( y = 0.278x - 14.229 \):
