Questions 3

What conclusion is most correct about the Experimental Design shown here with the response in the far right column?

ICBB Question 3

Options:

A.

No factor has enough statistical confidence greater than 95% to have an impact on the response rate

Constant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more

C.

If the Adv is increased from the low level to the high level, the response rate increases

D.

The response level is statistically concluded to only need the Adv and Bev factors set at the low level to get the largest response rate

E.

This design does not have enough experimental runs to conclude anything as evidenced by the lack of P-values in the MINITABTM output

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

ICBB Question 6

Options:

A.

The independent variable is the reactant

B.

If the reactant was 10 units, with 95% confidence we would expect a minimum yield of 148 units

C.

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

D.

A reactant value between 6 and 8 units yields around 40 to 60

E.

When the reactant increases, the expected yield would increase
