Coin collecting is big business around the world. As an illustration, there are more than 500,000 American coins and more than 100,000 Canadian coins for sale/auction on Ebay. Moreover, there are dozens of other coin auctions every month. There are three critical factors that determine the value of a coin. They are rarity, condition, and demand. Condition is now measured on a 70-point scale where 0 is very poor and 70 is perfect. To determine how condition affects price a random sample of auction sales of a 1925 Canadian nickel (a relatively rare coin) was drawn. The auction price ($Canadian), including buyer’s premium and the condition were recorded over the past 3 years. a. Draw a scatter diagram

b. What does the graph tell you about condition and price?
