ach year, a group surveys 50,000 households to study internet usage. In one area of the study, the group is interested in nding out how many hours a day the household spends streaming video from the internet. Describe the five basic steps in statistical study with an example of their application below. D. Use the sample statistics to infer the population parameters. In this case, the group estimates how many households have internet access. A. Act on the results. In this case, we determine that we need to have more households stream internet video. B. Repeat your study. In this case, we find a new sample to discover their internet usage. C. Draw conclusions to determine what you learned and whether you achieved your goal. In this case, we discovered the average time per day that a household spends streaming internet video. D. Draw conclusions to determine what you learned and whether you achieved your goal. In this case, we learned that some households use the internet to check email.
