This applet allows users to drag sliders to change the population proportion, confidence level and sample size. The applet helps users visualize the meaning of the phrase "C% confidence," by showing ...

Confidence Interval Estimate: a range of values so constructed that a specified proportion of the intervals costructed that way would contain the true value of a parameter. Critical Value: a point on ...
