:2.  A box contains 10,000 tickets.  Neither the box average
nor the box SD are known. It is known that the box histogram
follows the normal curve very closely. <p>

Two tickets are drawn at random from the box.  The numbers
on the two tickets are 1 and 3.  A 95% confidence interval for
the box average is closest to <p>

a.  from 1 to 3  <p>

b.  from -1 to 6  <p>

c.  from -7 to 11  <p>

d.  from -11 to 15  <p>

e.  It is hopeless to find 95% confidence intervals for     
such small samples.  <p>
