Due to small sample size, researchers used a computer to perform an exact confidence interval for a sample proportion. How should the interpretation of the confidence interval differ from standard methods:

a. The interpretation of the confidence interval is the same

b. Unlike methods that estimate confidence intervals using the CLT, computers are able to provide exact estimation of the true population proportion

c. Exact confidence intervals have smaller width compared to other methods

d. Exact confidence intervals from smaller samples have larger width compared to other methods
