Wow, this experiment must have been sponsored by the 'Ministry of Silly Designs'! I hope they have a backup plan for when the results turn out to be a total mess.

Wait, where's the control group? This whole thing looks a bit sketchy to me. I'm going to have to go with A on this one.

I think B is the correct conclusion here. Constant, Adv, and Bev are the only factors affecting the response rate.

Haha, this design is a real head-scratcher! I guess the experimenters got a little carried away with the 'high' and 'low' levels. E seems like the safest bet here.

I'm not sure about this one. The design seems a bit incomplete, but I would go with D. Minimizing the factors seems like the best way to get the largest response.

But what about C? Increasing Adv leads to an increase in the response rate.

I think the correct answer is B. The output clearly shows that Adv and Bev are the only factors with statistical significance at the 95% level.

It's clear that the other factors do not have enough statistical confidence to affect the response rate.

I agree, the data supports that only Adv and Bev have a significant impact on the response rate.

But what about the lack of P-values in the MINITABTM output? Doesn't that mean we can't conclude anything?

I disagree, I believe the correct conclusion is 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.

I think the correct conclusion is B) Constant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more.
