Based on the linear regression, how much would you expect a 0.55 carat diamond to cost? $1,800 $2,100 $2,500 $2,900 2. Based on the linear regression, how much would you expect a diamond that costs $5,500 to weigh? 0.72 carats 0.78 carats 0.81 carats 0.90 carats 3. You're surprised to learn that instead of ~$100, a 0.30 carat costs ~$800 carats. Which explanation would make sense? The linear regression is not accurate at predicting the cost of diamonds below 0.40 carats. ...
