Complete your assigned peer reviews:
- After you submit your initial good-faith attempt, continue to the ANSWER(S) page and review your instructor’s response. But please do not submit your corrected work yet.
- Within three days after the due date, return to this assignment and complete your assigned peer reviews (directions (Links to an external site.)).
Submit your corrected work:
- We all learn from mistakes (our own and our classmates’ mistakes). So please do not immediately correct your own mistakes. If possible, wait until you receive feedback from at least one of your peers.
- If necessary, correct your work and resubmit the entire assignment. Your instructor will only review and grade your most recent submission, so please do not refer to a previous submission.
Prompt
Use the applet to select 20 different random samples of 100 part-time college students. For each sample the applet calculates the 95% confidence interval. How many of the 20 random samples do not contain the population proportion? Is this what you expected? Explain.
