The table below lists measured amounts of redshift and the distances (billions of light-years) to randomly selected astronomical objects. Find the (a) explained variation, (b) unexplained variation, and (c) indicated prediction interval. There is sufficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. For the prediction interval, use a 90% confidence level with a redshift of 0.0126. Redshift 0.0234 0.0541 0.0722 0.0392 0.0443 Distance 0.0105 0.33 0.76 1.01 0.54 0.61 0.16 a. Find the explained variation. (Round to six decimal places as needed.)
