Answer to Question 1

External data are generated or recorded by an entity other than the researcher's organization. Traditionally, this information has been in published form, but today computerized data archives and electronic data interchange make external data as accessible as internal data. Because secondary data have value, they can be bought and sold like other products, and channels of distribution include (1) libraries, (2) the Internet, (3) vendors, and (4) producers. Classifying external secondary data by the nature of the producer of information yields five basic sources: periodicals, government sources, media sources, trade associations, and commercial sources.

Answer to Question 2

B
The null hypothesis, written as H0, always states the a population parameter is equal to a certain value.
