A new Pew Research Center survey explores public views on artificial intelligence (AI) in health and medicine. Based on the survey results from a large random sample of US adults, the 90% confidence interval to estimate the population proportion of all adults in the US who say that thinking about the use of AI in health and medicine makes them uncomfortable is between 0.456 and 0.638.

Based on the 90% confidence interval to estimate the unknown population parameter, provide the following items: 1) The best pointestimate for the unknown population parameter. Be sure to include the appropriate symbol for the estimate. 2) The value of the 90% margin of error. 3) The value of the standard error.
