A scientist measured the speed of light. His values are in?km/sec and have? 299,000 subtracted from them. He reported theresults of 30 trials with a mean of 756.23 and a standard deviationof 108.68.
?a) Find a 95?% confidence interval for the true speed of lightfrom these statistics.
?b) State in words what this interval means. Keep in mind thatthe 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?
