Interpreting technology: The following display from the TI-84 Plus calculator presents the least-squares regression line for predicting the price of a certain stock ()/) from the prime interest rate in percent (x). LinReg y = a+bx a = 2.41123442 b = 0.31168927 r= = 0.4378060376 r = 0.66166913 Part 1 of 3 X 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: y = 2.41133442 + .31168927x Correct Answer: y = 2.41123442 +0.31168927xPart 2 of 3 V What is the correlation between the interest rate and the yield of the stock? The correlation coefficient is .66166913 Part: 2 / 3 Part 3 of 3 Predict the price when the prime interest rate is 6.5%. Round the answer to at least four decimal places. When the prime interest rate is 6.5%, the price is predicted to be
