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

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

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

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

When the cutting speed increased from low to high level, the tool age increases

Quarter Fractional experiments can exist for those with 4 factors

Resolution V design is desired while controlling costs of experimentation

All of these answers are correct

SPC Charts are used extensively in different business and decision-making environments. In this example a vendor is being selected based on speed of delivery. Which of the conclusions would help you pick a vendor for your needs regarding lead-time of delivery from your vendors? (Note: There are 4 correct answers).

Vendor B as it has a better consistency (lower variance) on lead time

Vendor B as Vendor A shows a situation out of control as shown in red

Vendor B as the Control Limits are much narrower than Vendor A

Vendor B with higher lead time, but a process with much narrower Control Limits

Vendor A with a much shorter lead time in delivery

Vendor B as it has a better consistency (lower variance) on lead time

Vendor B as Vendor A shows a situation out of control as shown in red

Vendor B as the Control Limits are much narrower than Vendor A
