In area B, the new customers, another sample of 200 files shows 12 have defaulted on their loans. At a 10% level of significance can we say that the default rates are the same or different?

In a sample of 16 sales calls it was found that she closed the contract for an average value of 108 dollars with a standard deviation of 12 dollars.

Determine the domain and the range of the relation, and tell whether the relation is a function. {(8,1), (28, -9), (33,1), (8,0), (55,0)} The domain is {(8,28,33,8,55), (1, -9,1,0,0), Not a Function}. (Use a comma to separate answers as needed. Type each answer only once.) That's incorrect. To find the domain of the relation, look at the ordered pairs. If we denote the ordered pairs by (x,y), the set of all x-values is the domain of the relation.
