The dilemma faced by the Fed when considering monetary policy is the choice between interest rates and reserve.</span>
If you have samples of n 1 equals 22 and n 2 equals 20, in performing the pooled-variance t test, you have 40 degrees of freedom.
The t-test method is a method where we analyze two sets of data which both these data are independent of each other. This pooled variance test helps us in getting the overall variance in both these different sample sets when we know that both the sample sets are almost equal.
To calculate degrees of freedom, we have the formula
df = n1 +n2 -2
According to the question, n1= 22 and n2= 20
Therefore, degree of freedom= 22 +20 -2 = 40
Hence, degree of freedom is 40.

Answer:
D) specialty
Explanation:
When we are told that <u>Danica is not looking for any new washing machine</u> just to replace the old one she has, we know for sure she isn´t simply shopping (which is buying for just buying... simply to get newer things).
By knowing she is dedicating time and effort into finding her new washing machine we can be sure she isn´t looking for a convenience product (which, as you may know, is a product that you buy without thinking too much about it... <u>it simply is convenient</u>).
We can also know for sure that she is not looking for an unsought product since she is making a complete research and product comparison.
Although Danica is planning a lot and gathering lots of information about this new washing machine, <u>nothing indicate us she is planning on spending extra money</u> on a exclusive washing machine, leaving us with the only possible answer:
D) Specialty product. A product that she really wants, know´s why she wants it (information gathering), and will actively seek to purchase it.
