Constructing and Interpreting Confidence Intervals. In Exercises use the given sample data and confidence level. In each case, (a) find the best point estimate of the population proportion p; (b) identify the value of the margin of error E; (c) construct the confidence interval; (d) write a statement that correctly interprets the confidence interval.
From a 3M Privacy Filters poll in which respondents were asked to identify their favorite seat when they fly: n = 806, x = 492 who chose the window seat. Use a 99% confidence level.
Step 1 of 4</p>
Given x=492 , n=806
a)The best point estimate of the population proportion p=x/n
Step 2 of 4</p>
b)The margin of error E=2.58
