What conclusion is most correct about the Experimental Design shown here with the response in...

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

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

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

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