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

Question 2

Which of the following statements is true concerning the relationship between standard error and sample size?
 
  a. there is a positive relationship
  b. there is an inverse relationship
  c. as sample size decreases, the standard error decreases
  d. as sample size increases, the standard error increases
