Prompt
Each time you select the Click to generate a random sample of 100 students button below, the applet
generates a random sample of 100 part-time students,
calculates the proportion of the sample that are female, and
calculates the 95% confidence interval for the sample.
Use the applet to select 20 different random samples of 100 part-time college students. For each sample, note whether the population proportion is contained within the sample’s 95% confidence interval. How many of the 20 confidence intervals do not contain the population proportion? Is this what you expected? Explain.
