3. ARCHERY In an Olympic archery event, the center of the target is set exactly
130 centimeters off the ground. To get
the highest score of ten points, an archer
must shoot an arrow no further than
3.05 centimeters from the exact center of
the target.
a. Write an ABSOLUTE VALUE inequality to
represent the possible distances d
from the ground an archer can hit the
target and still score ten points.

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
