Questions # 2:

The Japanese born function of a Kaizen event utilizes a specific, step-by-step approach meant to bring about major changes to a process.

Options:

A.

True


B.

False


Expert Solution
Questions # 3:

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

Question # 3

Options:

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
