Question 9
The size of the sampling error is ________.
Directly related to the sample size—in other words, the larger the sample size, the larger the sampling error
Directly related to the population mean—in other words, the larger the mean, the larger the sampling error
Inversely related to the sample size—in other words, the larger the sample size, the smaller the sampling error
Inversely related to the population standard deviation—in other words, the smaller the standard deviation, the larger the sampling error
Question 15
Bones Brothers & Associates prepare individual tax returns. Over prior years, Bones Brothers has maintained careful records regarding the time to prepare a return. The mean time to prepare a return is 90 minutes and the standard deviation of this distribution is 14 minutes. Suppose 100 returns from this year are selected and analyzed regarding the preparation time. What assumptions do you need to make about the shape of the population distribution of all possible tax preparation times to make inferences about the mean time to complete a tax form?
The population distribution is skewed to the right.
The population distribution is skewed to the left.
The population distribution is normal.
The shape of the population distribution does not matter.
Directly related to the sample size—in other words, the larger the sample size, the larger the sampling error
Directly related to the population mean—in other words, the larger the mean, the larger the sampling error
Inversely related to the sample size—in other words, the larger the sample size, the smaller the sampling error
Inversely related to the population standard deviation—in other words, the smaller the standard deviation, the larger the sampling error
Explanation / Answer
14. c) Inversely related to the sample size—in other words, the larger the sample size, the smaller the sampling error
15. d) The shape of the population distribution does not matter.
