Question
Speed of light In 1882 Michelson measured the speed of
light (usually denoted c as in Einstein’s famous equation
E = mc2
). His values are in km/sec and have 299,000
subtracted from them. He reported the results of 23 tri-
als with a mean of 756.22 and a standard deviation of
107.12.
a) Find a 95% confidence interval for the true speed of
light from these statistics.
b) State in words what this interval means. Keep in mind
that the speed of light is a physical constant that, as
far as we know, has a value that is true throughout the
universe.
c) What assumptions must you make in order to use your
method?
