Taking this class has made you intellectually curious. I’m serious! So, you decide to
see whether Edison light bulbs last as long as the package says they do; according to
the package: α = 1200 hr and σ = 180 hr. Along with your physics major roommate,
you construct a bank of 100 light bulbs and watch them round the clock to see when
they burn out. The mean of your sample is 1170 hours. Does this constitute evidence
of consumer fraud by Edison light bulbs if α = .05?
