Do managers really have a large sample size bias? Because you cannot survey managers easily, this exercise will use surrogates. Ask any five seniors majoring in business administration who have not taken a marketing research class the following questions. Indicate whether each of the following statements is true or false.

a.   A random sample of 500 is large enough to represent all the full-time college students in the United States.                   True or False.

b.   A random sample of 1,000 is large enough to represent all the full-time college students in the United States.                True or False.

c.   A random sample of 2,000 is large enough to represent all the full-time college students in the United States.                True or False.

d.   A random sample of 5,000 is large enough to represent all the full-time college students in the United States.                True or False.
