Given the equation of regression line is y = -4.5x - 5.8, what is the best predicted value for y given x = -9.3? Assume that the variables x and y have a significant correlation.
PLz help me anyone

You have to substitute the value of x into the equation and solve for y:
y = -4.5x - 5.8
y = -4.5 * -9.3 - 5.8
y = 36.05

For a pattern to be picked randomly the person-friendly question you may answer is " Does each physique have the comparable danger of being picked every time you go with somebody". If the respond is confident then your pattern has been picked randomly. to respond to your first question purely positioned a bite of paper in a hat with everyones selection on it and p.c.. out one after the other till you have 4. (a) no longer random because of fact as quickly as you verify to p.c.. your pattern this manner everybody different than the 1st 4 have 0 danger of being picked. all the different techniques (b), (c) and (d) you may pose an analogous argument to that in the process (a)

Just plug the x = -9.3 into the equation and see what you get for y. That's all there is to it!
