In-Lab Project: Estimating a Population Proportion with Confidence Example Solutions In this project, we are going to investigate using the sample proportion as a way of estimating the population proportion. For the purpose of this activity, we are going to assume that the lab section is a representative random sample of the UM student body. Follow the steps below to estimate the population proportion. 1. Determine a question to investigate by filling in the following question. “What proportion of UM students______ have played dominoes before ____?” 2. Once the question has been determined, the instructor will pose the question to the class using the Qwizdom system. Record the results below and provide an estimate of the population proportion of all UM students that ______ (that is, report the sample proportion). # of students responding: 28 # of student who responded “yes”: 12 Sample proportion of student who responded “yes” : (symbol and value) ˆ p =12/28 = 0.4286 0.43 3. (a) The estimate in part (2) is a sample proportion. About how far away from the population proportion
