**Translating Survey Results to a Confidence Interval**To better understand survey results, we often need to translate them into a confidence interval, allowing us to approximate the level of confidence we can have in the data. Here's an example:**Survey Context**: A survey of 1000 adults in a country revealed that 65% of respondents believe speaking the national language is crucial to national identity. The survey's margin of error is ± 3.4%.**Confidence Interval Calculation**: The margin of error is added and subtracted from the percentage to create a confidence interval. In this case:- Lower limit: 65% - 3.4% = 61.6% (shown as 0.616 in decimal form)- Upper limit: 65% + 3.4% = 68.4% (shown as 0.684 in decimal form)Thus, the confidence interval for this proportion is (0.616, 0.684).You are also asked to identify the confidence level of this interval. This step requires statistical methods or graphical tools to determine and would be expressed as a percentage. Typically, common confidence levels are 90%, 95%, or 99%. The exact level here needs to be calculated based on the statistical methodology or tools.This approach aids in understanding the dispersion and reliability of survey data, offering a more nuanced picture of public opinion.

Translate the statement into a confidence interval. Approximate the level of confidence. In a survey of 1000 adults in a country, 65% said being able to speak the language is at the core of national identity. The survey's margin of error is ±3.4%. The confidence interval for the proportion is (0.616 , 0.684 ). (Round to three decimal places as needed.) The interval is a % confidence interval. (Round to one decimal place as needed.)
