A scientist measured the speed of light. His values are in km/sec and have 299,000 subtracted from them. He reported the results of 30 trials with a mean of 756.23 and a standard deviation of 108.68.
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?
