• BConstant, Adv and Bev are the only factors statistically affecting the response rate with 95%
• CIf the Adv is increased from the low level to the high level, the response rate increases
• DThe response level is statistically concluded to only need the Adv and Bev factors set at the low
• EThis design does not have enough experimental runs to conclude anything as evidenced by the
