a survey it conducted of 1,284 U.S. military veterans: 57 percent
of U.S. veterans approve of Trump’s conduct as commander-in-chief
of the U.S. armed forces. The survey employed probabilistic
sampling.
Construct a 98 percent confidence interval for the true
proportion of American veterans that approves of Trump’s conduct as
commander-in-chief.
