SOC215 F16 | Oliver Assignment 5: Due October 16 th by 11:59 PM 1. Suppose you are taking a random sample of students at UM-Flint. How does the standard error (SE) of the mean change when (for each problem, circle the best answer): A) The sample size increases from 50 to 1500? SE gets larger SE gets smaller SE stays the same B) The sample size decreases from 200 to 20? SE gets larger SE gets smaller SE stays the same SE gets smaller SE stays the same C) The sample size is tripled? SE gets larger 2. The mean number of years of education completed in the United States is 13.43 with a population standard deviation of 3.08 years. Imagine that you take a subsample of 150 people in the United States. What is the probability that your sample mean will be between 13 and 14? Show your work or explain how you arrived at your answer. 1 SOC215 F16 | Oliver 3.
