. If false explain why. Choose the correct answer below. Only I is false.

The sample size needed to estimate a population mean is directly proportional to the population variance b. The sampling frame is a list of every item that appears in. If you increase the sample size the ability to detect differences increases whichreduces Type II error.

C Expanding the sample size can increase the power of a hypothesis test. None of these choices. If the sample size is large enough almost any null hypothesis can be rejected.

The samples are only a portion of the population. Which of the following statements about sample size is false. D A larger sample size would increase the power of a significance test.

The larger the sample variance the larger the sample size that is required. D Reducing the significance level α can increase a tests effectiveness. C There is no way to prevent sampling error short of taking a census of the entire population.

B Increasing the sample size will reduce the size of the sample mean used to estimate the population mean. Which of the following statements is false. Surveys based on larger sample sizes have larger standard errors.

The sampling frame refers to a list of an item which responds to the question and not the ones which do not respond to the. Only III is false. The Central Limit Theorem is considered powerful in statistics because it works for any population distribution provided the sample size is sufficiently large and the population mean and standard deviation are known.

4 rows Sampling error can occur when the sample mean differs from. Increasing the sample size will always reduce the size of the sampling error when the sample mean is used to estimate the population mean. The sample size of the survey should at least be a fixed percentage of the population size in order to produce representative results.

A smaller sample size would increase the effectiveness of a hypothesis test. I II and III are false. It is directly proportional to the population variance.

The precision of an estimator does not depend on the size of the sample.
