Overview
Chapter 8 Lecture Questions
1. Given a sampling distribution of means, how are the mean and standard deviation determined (calculated)? *Be sure to explain any formulas needed
2. What happens to the standard deviation as the sample size increases?
3. If an original sampling is not normal, how many must we sample to say it is approximately normal?
4. Given a sampling distribution of proportions, how are the mean and standard deviation determined (calculated)? *Be sure to explain any formulas needed
5. Where do you go in StatCrunch to determine the probability of an event occurring in the sample (What buttons do you click)?
