Chapter 12, Problem 35E

(a)

To determine

To explain do you think the proposed sampling method is appropriate.

Answer to Problem 35E

Yes, it is.

Explanation of Solution

It is given the sampling method in which we want to know what percentage of local doctors accept medical patients. So, they have called the offices of $50$ doctors randomly selected from local yellow page listings. Thus, we think that the proposed sampling method is appropriate because only local doctors will have a chance to be selected.

(b)

To determine

To explain do you think the proposed sampling method is appropriate.

Answer to Problem 35E

No, it is not.

Explanation of Solution

It is given the sampling method in the question that we want to know what percentage of local businesses anticipated hiring additional employees in the upcoming month. So, they have randomly selected a page from yellow page and call every business listed there. Thus, we can say that this is not appropriate since the Yellow Pages may group businesses by location. All of the businesses in that area may be more inclined or disinclined to hire.
