Question
Engagement Activity: Probability and samples - The Distribution of sample Means samples are variable. If you take two (or three) separate samples from the same population, the samples will be different from one another because they will contain different individuals, attributes, and sample means. As a result, using different samples to predict population parameters will result in different estimates of those parameters. For example, the following image shows a population of 100 people. The population has been stratified for ethnicity and gender based on data from the U.S. Census, Bureau 2010 for the state of Texas. Data source and gender distribution based on data from the U.S. census Bureau 2010. "State & county Quickfacts: state of Texas". Retrieved August 9, 2011 For each of the samples, click on the respective tab (Sample 1, sample 2, and so forth) at the top of the image to see the sample. Then for each of the four ethnicities listed, count the number present in the sample and use the counts to predict the diversity in the population. To get credit for predictions, select the percentages appropriate for each ethnicity from the dropdown menus in the random sample column of the following table. Do you think you can tell which sample most closely represented the actual population? No YesExplanation / Answer
Hence the Sample3 is most Closely represented the Actual Population because the sum of all percentages of Sample3 is 75%.
So i think we can tell the most closely represented the Actual Population.
So answer is YES.
