Which of the following statements are true and which are false? Justify your answers! (d) The standard error of the proportion will increase when the sample size gets larger. (e) A point estimator is better than an interval estimator because it is more precise. (f) The sample mean is an unbiased estimator of the population mean but it is not always con-sistent, if the population variance is very large.

Step 1
As the sample size $n$ increases, the denominator of the fraction inside the square root increases, which in turn causes the standard error to decrease. Show more…

Which one of the following statements is false? a. The standard error of a sample statistic measures, roughly, the average difference between the values of the statistic and the population parameter. b. The standard error measures the variability of a population parameter. c. The standard error of a sample proportion decreases as the sample size increases. d. Assuming a fixed value of s = sample standard deviation, the standard error of the mean decreases as the sample size increases.
Which of the following statements is FALSE? A) Estimators are the measures used to estimate population parameters. B) Point estimates do not provide any indication of the magnitude of the potential error in the estimate. C) Convenience sampling is an example of a probabilistic sampling method. D) A confidence interval is a range of values between which the value of the population parameter is believed to be.
