A box 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.
