Multiple Choice

Confidence levels allow the researcher to have some idea of how closely their samples reflect the parameter.Which of the following statements about confidence levels is not true?

• A) if a simple random sample is used, probability theory suggests that researchers can be 68 percent sure the estimates of that sample fall within one standard error of the parameter
• B) if a simple random sample is used, probability theory suggests that researchers can be 95 percent sure that estimates of that sample fall within two standard errors of the parameter
• C) if a simple random sample is used, probability theory suggests that researchers can almost positive (99+ percent) that estimates of that sample fall within three standard errors of the true value
• D) if a simple random sample is used, probability theory allows the researcher to know with certainty that they have accurate data
