Estimate a population total, mean or percentage using data from a sample survey; develop a margin of error through the use of simulation.
Algebra 1 Example: Based on a survey of 100 households in Twin Lakes, the newspaper reports that the average number of televisions per household is 3.5 with a margin of error of ±0.6. The actual population mean can be estimated to be between 2.9 and 4.1 television per household. Since there are 5,500 households in Twin Lakes the estimated number of televisions is between 15,950 and 22,550.
Clarification 1: Within the Algebra 1 course, the margin of error will be given.
