Questions A-C 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 standarddeviation 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 conTiaence 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,O C. 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.Click to select your answer(s).MacBook AirF11F12F10B0 F3A00 E4F8F9F5F6F7788&*%3D478TY6 A scientist measured the speed of light.

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?a) A 98% confidence interval for the true speed of light is ( km / sec, km/ sec(Round to two decimal places as needed.)b) In words, what does the 98% confidence interval mean?O A. With 98% confidence, based on these data, the speed of light is between the lower and upper bounds of the confidence interval.O B. Any measurement of the speed of light will fall within this interval 98% of the time.OC. For all samples, 98% of them will have a mean speed of light that falls within the confidence interval.O D. The confidence interval contains the true speed of light 98% of the time.Click to select your answer(s).MacBook Air吕0 F3F12A00 F4F9F10F7F8F5%&*567R* C∞
