What is the relationship between diamond price and carat size? 307 diamonds were sampled and a straight-line relationship was hypothesized between y = diamond 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 Std Error T P
Constant -2298.36 158.531 -14.50 0.0000
Size 11598.9 230.111 50.41 0.0000

R-Squared 0.8925 Resid. Mean Square (MSE) 1248950
Adjusted R-Squared 0.8922 Standard Deviation 1117.56

Which of the following assumptions is not stated correctly?
◦ The values of ε associated with any two observations are dependent on one another.
◦ The variance of the probability distribution of ε is constant for all settings of the independent variable.
◦ The probability distribution of ε is normal.
◦ The mean of the probability distribution of ε is 0.
