Construct the linear regression equation and explain the slope of the equation statistically. Regression equation is Y = a+bx which is Y =23.974 - 2.014x The meaning of a = 23.974 The meaning of b = -2.014 Every increase in an hour of weekly overtime the sleeping hours daily will decrease by 2.014 (4 marks) Using the linear equation constructed, predict the daily sleep hours if the weekly overtime hours is 20. Explain if this is an accurate prediction. Using the linear equation constructed, we predicted that the daily hours to be
