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 trials 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?
