: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.
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
a. from 1 to 3
b. from -1 to 6
c. from -7 to 11
d. from -11 to 15
e. It is hopeless to find 95% confidence intervals for such small samples.
