Census ~ In 2020, Pew Research conducted a poll to examine how likely a person was to participate in the 2020 US Census based on their age. In a random sample of US adults aged 50 years or older, 85.63% said they were likely to participate in the Census. The estimated standard error of the sample proportion is 0.0064. A normal distribution can be used to model the sampling distribution of sample proportion. The researchers wish to construct a 95% confidence interval for the actual proportion of US adults aged 50 years or older who said they were likely to participate in the Census. What is the upper bound for the 95% confidence interval? Give your answer to 4 decimal places.
