2. Question: Confidence intervals of the unknown parameters can be: a. A confidence interval for the proportions of binomial populations are less confidence than the confidence interval for the means of Normal populations. b. A confidence interval is an interval of values computed from a given sample data and test criterion which is likely to include the true population parameter. c. The 95% confidence intervals for the chi-square distribution is less efficiency than the F- distribution. d. A confidence intervals for the difference between means of two population using Z- distribution is more accurate than using T -distribution. e. A 99% confidence interval for the mean with unknown equal variances has a higher probability of including the population parameter than the case of unknown unequal variances.
