Question # 10

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

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

Question # 12

For the data shown here which statement(s) are true? (Note: There are 2 correct answers).

A.

With 95% confidence, we cannot conclude if the samples are from three Normal Distributions

B.

With greater than 95% confidence, we conclude the samples are from Non-normal Distributions

C.

If we wanted to compare the Central Tendencies of these three samples we would use the one way ANOVA test

D.

If we wanted to compare the Central Tendencies of these three samples we could use Mood’s Median test

E.

If we wanted to compare the Central Tendencies of all three samples we could use the Mann-Whitney test

Question # 13

Which statement(s) are correct about the Regression shown here? (Note: There are 2 correct answers).

B.

The relationship between outside temperature and number of customers per hour is a Linear Regression

C.

The dashed lines indicate with 95% confidence where all of the process data should fall between

D.

The dashed lines indicate with 95% confidence the estimate for the Quadratic Regression Line

E.

The predicted number of customers per hour is close to 5 if the outside temperature is 10 deg C
