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.

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.

The accompanying data table lists measured voltage amounts
supplied directly to a family's home. The power supply company
states that it has a target power supply of 120 volts. Using those
home voltage amounts, test the claim that the mean is 120 volts.
