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.

There is a fixed cost associated with procuring the diamond and offering it for
sale, meaning that small diamonds have a relatively high price.

The diamond is very high quality as measured by other metrics (e.g., cut,
clarity, color).

All of the above.
4.
If a residual is negative, what does it mean about the observed




/

, value?
The predicted value is greater than the observed value.
