Let's revisit the cilantro scenario from theModule 2 - Discussion: The Chance Model (Theory-Based)assignment.

Based on experience, you believe that less than 15% of the population of your city dislike the taste of cilantro. Two-hundred people were randomly selected from your city and questioned about their like or dislike of the taste of cilantro. Thirty-two of those questioned stated they disliked the taste of cilantro.

Run Applet

just needs some guidance on how attack these questions.

• Use the 2SD method to estimate the true proportion of the population of your city that dislikes the taste of cilantro. State the resulting confidence interval in both forms - the interval notation and the sample proportion the margin of error notation.
• Write the interpretation of this confidence interval.
• Use the theory-based method to estimate the true proportion of the population of your city that dislikes the taste of cilantro with a 95% confidence interval. State the resulting confidence interval in both forms - the interval notation and the sample proportion the margin of error notation.
• Write the interpretation of this confidence interval.
• Use the theory-based method to estimate the true proportion of the population of your city that dislikes the taste of cilantro with an 88% confidence interval. State the resulting confidence interval in both forms - the interval notation and the sample proportion the margin of error notation.
• Write the interpretation of this confidence interval.
