Which of the following statements is TRUE? O a The larger the size of the sample, the greater is the length of the confidence interval. O b The smaller the confidence level, the greater is the length of the confidence interval. Oc. The larger the size of the sample, the lesser is the length of the confidence interval. O d. The larger the confidence level, the lesser is the length of the confidence interval. Z-distribution is used when the population standard deviation is unknown and the sample size is greater than 30 O b. the population standard variance is unknown and the sample size is less than 30 Oc. the sample standard deviation is given and the population size is less than 30 Od. the sample size is greater than 30 and the population variance is known This refers to the degree of certainty that the true population parameter falls within the constructed interval estimate. Degrees of certainty Ob. Confidence interval O c. Degrees of freedom O d. Confidence level
