Mathematics
(1 point) (Hypothetical.) We are given a box full of thousands of tickets labeled 0 or 1. We want to estimate the unknown proportion p of 1s in the box. To do this, we randomly draw 200 tickets and add them up: it so happens they add up to 124. Enter values in decimal form, rounded to four decimal places (or more). We estimate the proportion of 1s in the box to be 124/200 . Attach a give-or-take value to this estimate. (That is, estimate the standard error.) .0343 For an approximate 85% confidence interval, about how many standard errors should be added to and subtracted from the estimate? 1.44 Set up an approximate 85% confidence interval for the unknown proportion of 1s that are in the box.
