# Question

The table below lists measured amounts of redshift and the distances (billions of light-years) to randomly selected clusters of galaxies. For the prediction interval, use a 90% confidence level with a redshift of the cluster Fiydra of 0.0126.
Find the
(a) Explained variation,
(b) Unexplained variation, and
(c) Indicated prediction interval. In each case, there is sufficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions.
