Posting Instructions Learning Outcome: To find a confidence interval for your binomial random variable. Overview: We learn in this lesson that we can never be 100% confident in any statistic. Let's use the binomial random variable you created in Discussion 4 to create a few confidence intervals. Step 1: Rewrite your variable and your p from Discussion 4. p=0.384 Step 2: Using the city population of your original sample, create and interpret a 95% confidence interval for your binomial random variable. Round your answer to the nearest hundredth of a percent. Step 3: Using the same sample size, create a 99\% confidence interval. Talk to us about how your confidence interval changed from Step 2 when the confidence level is increased. Step 4: Using a different city population, create a 95% confidence interval for your binomial random variable. Talk to us about how your confidence interval changed from Step 2 when the sample size has increased (or decreased, depending on your new city).
