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?

A.

F Test

B.

Test for Equal Variance

C.

Chi Square Test

D.

One-Sample t-Test
