Unformatted text preview: d the mean and standard deviation. Sampling Distribution of the Sample Proportion (continued Checkpoint 3 - Modeling and Inference Sampling Distribution of the Sample Proportion Begin by Checking the conditions The drivers were randomly selected. Successes: 48 ≥ 10, Failures: 152 ≥ 10 Population Size (# American Drivers) is very large. Conclusion: The Distribution is approximately normal. The expected value for the sample proportion is µ (ˆ) = p 48/200 = 0.24 The standard error is σ (ˆ) = 0.24 ∗ 0.76/200 ≈ .03 p Sampling Distribution of the Sample Proportion (continued Checkpoint 3 - Modeling and Inference Sampling Distribution of the Sample Proportion Visualizing the CLT - The Bell Curve Sampling Distribution of the Sample Proportion (continued Checkpoint 3 - Modeling and Inference Sampling Distribution of the Sample Proportion Confidence Intervals Recall ˆ The Confidence Interval for p is: zα /2 = standardized z-score with an area α /2 above it. http://onlinestatbook.com/stat_sim/conf_...
