What conclusion is most correct about the Experimental Design shown here with the response in the far right column?
A . No factor has enough statistical confidence greater than 95% to have an impact on the response rate
B . 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
Answer: D
