Truncating and Confidence Interval WORKSHEET
Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.
Truncating and Confidence Interval WORKSHEET DESCRIPTION
In this truncating and error intervals worksheet, students work on truncating numbers and understanding how truncation affects error intervals.
Section A focuses on truncating numbers to various levels, such as integers, powers of ten, decimal places, and significant figures. This section is well structured in tabular form in order to help students gain confidence in working with different forms of truncation.
Section B requires students to identify the lowest and highest possible values after truncation and then calculating the error intervals for various truncated numbers. Finally, students must approximate the areas of shapes by truncating and rounding measurements, comparing the outcomes and understanding how different methods affect the results.
