Shown below is a portion of a computer output for a regression analysis relating supply (y in thousands of units) and unit price (x in thousands of dollars). ANOVA Regression Residual Intercept X df 1 39 Coefficients 54.076 0.029 SS 354.689 7035.262 Standard Error 2.358 0.021 a. Calculate the t statistic. Let a = .05.Type in your t statistic to 3 decimals: Do you Reject or Fail to Reject the Null Hypothesis? Type in Reject or Fail to Reject: b. Calculate your Fisher statistic and round to 3 decimals: c. Compute the coefficient of determination Round to 3 decimals: 0.421 d. Compute the coefficient of correlation Round to 3 decimals: 0.177 e. Predict the supply (in units) when the unit price is $50,000.: 56.976
