Texas Instruments: Confidence Intervals for Means
This set contains questions about statistics regarding confidence intervals for means. Students analyze the relationship, concerning means, between confidence levels and the length of confidence intervals.
Texas Instruments
Texas Instruments: Inference for Correlation and Regression
In this activity, students test if a significant relationship exists between a bivariate data set, and then calculate the confidence and predictive intervals. They also improve the interval-prediction capabilities by automating the process.
Texas Instruments
Texas Instruments: Tests of Significance
Students understand how tests of significance can be performed with confidence intervals. They use a simulation to clarify the meaning of a hypothesis. Students examine large sample tests for a proportion, mean, difference between two...
Texas Instruments
Texas Instruments: Confidence Intervals for Proportions
The student will use the TI-83 Plus/TI-84 Plus to calculate confidence intervals for proportions.
