Unformatted text preview: interval/index.html The Confidence Interval measures the capture rate for our method of finding CI Sampling Distribution of the Sample Proportion (continued Checkpoint 3 - Modeling and Inference Sampling Distribution of the Sample Proportion CONFIDENCE INTERVAL Confidence Interval for p : The margin of error means that we are (1-α )100% confident that the population proportion is within ±ME of the sample proportion. or: we are (1-α )100% confident that the true proportion (of something) is within ±ME % of the estimated proportion. EX: The estimated Mean GPA from a random sample of ¯ 1000 students is x = 2.7 with a ME of .025. This means that we can be 95% confident that the mean grade point average in the population is 2.7 plus or minus 0.025, since the margin of error is 0.025. Sampling Distribution of the Sample Proportion (continued Checkpoint 3 - Modeling and Inference Sampling Distribution of the Sample Proportion Common Values of zα /2 ∗ zα /2 = 1.645 or 1.65 for 90% confidence interval ∗...
