Janine is studying the relationship between the size of a diamond (in carats) and its price. She obtains size and price data for a random sample of 64 diamonds. Here is computer output from a least-squares regression analysis on her sample:
\begin{tabular}{lrrrr}
Predictor & Coef & SE Coef & T & P \\
\hline Constant & 8.00 & 60.76 & 0.13 & 0.90 \\
Carat & 2722.34 & 259.92 & 10.47 & 0.00 \\
S & R-sq & & &
\end{tabular}
Assume that all conditions for inference have been met.
Which of these is a confidence interval for the slope of the least squares regression line?
