What is the relationship between diamond price and carat size? 307 diamonds were sampled (ranging in size from 0.18 to 1.1 carats) and a straight-line relationship was hypothesized between y = diamon price (in dollars) and x = size of the diamond (in carats)The simple linear regression for the analysis is shown below. Least Squares Linear Regression of PRICE Predictor Variables Coefficient Error TP Constant -2298 36 158.531 14.50 0.0000 Size 11598.9 230.11150.41 0.0000 R-Squared Resid. Mean Square (MSE) 1248950 Adjusted R-Squared 0.8922 Standard Deviation 1117.56 Interpret the estimated y-intercept of the regression line. Select one : When a diamond is carats in size, we estimate the price of the diamond to be 2298.36 B. When a diamond is carats in size we estimate the price of the diamond to be $11,598.90 When a diamond is 11598.9 carats in size, we estimate the price of the diamond to be $2298.36 D. No practical interpretation of the yintercept exists since a diamond of carats cannot exist and falls outside the range of the carat sizes sampled
