Confidence Intervals for 2 Sample Proportions

Published on

Do senior citizens and college students have different memories about high school? The activity Confidence Intervals: 2-Sample Proportions involves investigating random samples from two populations from a large Midwestern city with respect to the question: "When you were in high school, did you have a hero?" How can responses from two random samples from each population be used to estimate the responses of all senior citizens and all college students in this city?

Confidence Levels for Means

Published on

Students will interpret a confidence level as the average success rate of the process used to produce an interval intended to contain the true mean of the population. Students will recognize that as the confidence level increases, on average, the confidence interval increases in width.
