For the following use the Spearman rank correlation coefficient
to test the claim. The overall scores and the prices for 10
randomly selected computers. The score is based on overall quality
of the computer. At a .05 sig. can you conclude there is a
correlation between price and score? Utilize excel to show your
work.
