Question 1 (3 points) ~/ Saved As the sample size increases, the margin of error __________ . O stays the same O may increase or decrease, depending on the sample mean 0 increases @ decreases Question 2 (3 points) A random sample of 49 scores from a population of scores in a common exam is selected. The average score, in the sample, is 84 with a standard deviation of 3.5. What is the 95% confidence interval for the average score of the population of scores? 0 77.0 to 91.0 0 83.0 to 85.0 O 80.5 to 87.5 0 83.5 to 84.5 Question 3 (3 points) J Saved In general, if we change a 95% confidence interval to a 99% confidence interval, we can expect __________ . G) the range of the confidence interval to increase 0 the range of the confidence interval to stay the same 0 the range of the confidence interval to decrease O the standard error to increase Question 4 (3 points) When the population standard deviation is unknown and the population has a normal or near-normal distribution, which distribution is used in developing an interval estimate of the population mean? Assume that the sample size is n. O t distribution with n degrees of freedom 0 t distribution with n + 1 degrees of freedom 0 t distribution with n - 1 degrees of freedom 0 normal distribution Question 5 (3 points) For the interval estimation of a population mean, if the population standard deviation is known and the sample size is large, the appropriate probability distribution to use is the __________ . Assume that the sample size is n. 0 normal distribution 0 t distribution with n degrees of freedom 0 t distribution with n - 1 degrees of freedom 0 t distribution with n + 1 degrees of freedom
