Abox is full of thousands of numbered tickets. we want to estimate the unknown average of all the numbers in the box. to do this, we draw 100 tickets at random. the numbers on these 100 tickets average out to 24 with a standard deviation of 5.
round your values to three decimal places.
we estimate the average of all the tickets in the box to be
attach a give-or-take value to this estimate. (that is, estimate the standard error.)
for a 94% confidence interval, about how many standard errors should be added to and subtracted from the estimate?
set up an approximate 94% confidence interval for the average of all the tickets in the box.
