Fom a random sample of 1,005 adults in the United States, it was found that 32 percent own an e-reader. Which of the following is the appropriate 90 percent confidence interval to estimate the proportion of all adults in the United States who own an e-reader? (A) 0.32 ± 1.960 ((0.32 0.68)/√1.005)
(B) 0.32 ± 1.645 ((0.32 0.68)/√1.005)
(C) 0.32 ± 2.575 √((0.32)(0.68)/ 1.005)
(D) 0.32 ± 1.960 √((0.32)(068)/1.005)
(E) 0.32 ± 1.645 √((0.32)(0.68)/1..005)
