Explanation The predicted value is obtained by using the formula: y ^ = b 0 + b 1 x Where, y ^ represents the predicted value of the response variable. b 0 represents the estimated value for the intercept β 0 . b 1 represents the estimated value for the slope coefficient β 1 . x represents the value of the predictor variable. Estimate for the slope coefficient is calculated by using the formula: b 1 = r s y s x Where, r represents the correlation value between x and y . s y represents the standard deviation of the variable y

Students have asked these similar questions

Suppose the relationship between Y and X is given by: Y = 25 - 3X + error By how much does the expected value of Y change if X decreases by 2 units?

Suppose the relationship between Y and X is given by: Y = 25 - 3X + error By how much does the expected value of Y change if X decreases by 1 unit?

What test involves an analysis of rate of change in Y per single point increase in X and what is the “predictor”?
