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 756.22 and a standard deviation of 117.14. a) Find a 98% 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? UD. The conidence intervai contains the true speea or lignt 98% or tne time. c) What assumptions must you make in order to use your method? Select all that apply. O A. The measurements arise from a random sample or suitably randomized experiment. O B. The data come from a distribution that is nearly normal. The data come from a distribution that is nearly uniform. O D. The measurements are independent. O E. The sample is drawn from a large population.
