Question 13

Which statement is NOT correct about the Fitted Line Plot shown here?

The independent variable is the reactant

If the reactant was 6 units, with 95 % confidence we would expect a minimum yield of 100 units

With at least 95% confidence, we can expect less than 10 units of Yield when the reactant is at a value of 1

A reactant value between 2 and 4 units yields around 20 to 40

When the reactant increases, the expected yield would increase

Correct Answer: B

Option B is incorrect. From the fitted line plot, if the reactant is 6 units, the yield can be estimated from the regression equation and the confidence interval/prediction interval. The regression line indicates a yield lower than 100 units when the reactant is 6 units. Therefore, claiming a minimum yield of 100 units with 95% confidence is incorrect.

Discussion

turbosiputOption: B

Correct answer is B?

InvisibleBeingOption: B

Correct answer should be B. If the reactant was 6 units, at 95% the expected value is in the middle of 50 and 100, and not a minimum value of 100.
