Questions # 23:

Sally and Sara sell flower pots at their garage sale. Sally motivates Sara mentioning that they will sell a minimum of 15 pots per day if the outside temperature exceeds 60o F. From a sample, whose population is assumed to follow a Normal Distribution, taken for 30 days at 60 degrees or more an average of 13.6 pots per day were sold with a Standard Deviation of 0.7 pots. For the sales accomplished above, what test would validate if they met their requirements?

Options:

A.

F Test


B.

Test for Equal Variance


C.

Chi Square Test


D.

One-Sample t-Test

Factorial Design


Questions # 25:

If an experiment has 5 factors and no replicates for a 2-level Experimental Design with 16 experimental runs which statement(s) are correct? (Note: There are 3 correct answers).

Options:

A.

The Main Effects for the 5 factors are not aliased or confounded but the 2-way interactions are confounded with the 3-way interactions


B.

The Main Effects are confounded with only 4-way interactions


C.

The Experimental Design is half-fractional


D.

The experiment has 8 experimental runs with the first factor at the high level


E.

The experiment has only 4 experimental runs with the 5th factor at the high level

C.

Inadequate information on class Means to make any statistical conclusions


D.

A visual comparison shows that class Means are not statistically different


E.

A visual comparison shows that class Means are statistically different
