You can use Minitab to answer the following questions. However, you should be able to calculate the slope and intercept of the least squares regression model by hand, which requires only the means and standard deviations of X and Y, and the correlation coefficient (here r = 0.9829).
- The intercept of the fitted regression line is closest to:
- The yield predicted by the regression model for a temperature of 150 degrees is closest to:
- The residual error for a temperature of 150 degrees is closest to:
- If the yield were measured in ounces instead of grams (note that 1 gram is 0.35274 ounces), the slope would change by a factor of:
- If the yield were measured in ounces instead of grams (note that 1 gram is 0.35274 ounces), the correlation coefficient would increase by a factor of:
