Question 18 This Test: 100 pts possible @ Submit Test 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 Distance 00231 003 0.0538 074 0.0724 089 0.0391 0.56 0.0439 0.62 0.0101 0.13 a. Find the explained variation. (Round to Six decimal places as needed.) b. Find the unexplained variation. (Round to six decimal places as needed.) c. Find the indicated prediction interval. billion light-years < y < billion light-years (Round to three decimal places as needed.)
