Part 1 of 3 Write the equation of the least-squares regression line. Use the full accuracy shown in the calculator output (do not round your answers). Regression line equation: $\hat{y}=2.26054252+0.34380511 x$ Part: $1 / 3$ Part 2 of 3 What is the correlation between the interest rate and the yield of the stock? The correlation coefficient is $\square$ .
