After taking a random start between 1 and 20 and then taking every 20th element from the sampling frame, Smith learned that 40% of the sample believed the company’s president was doing a good job. The calculated standard error was 3 percent. Assuming a normal distribution, this means that
a.   between 37% and 43% of the employees believe the president is doing a good job.
b.   you are 95% certain that between 37% and 43% of the employees believe the president is doing a good job.
c.   you are 68% certain that between 37% and 43% of the employees believe the president is doing a good job.
d.   you are 99% certain that between 37% and 43% of the employees believe the president is doing a good job.
e.   between one and twenty percent of the sample believes the president is doing a good job.
