Stephen Stigler determined in 1977 that the speed of light is 299,710.5 km/sec. In 1882, Albert Michelson had collected measurements on the speed of light ("Student t-distribution," 2013). Is there evidence to show that Michelson’s data is different from Stigler’s value of the speed of light? State the random variable, population parameter, and hypotheses. Random Variable = Speed of light. Population parameter = mean speed of light by Albert Michelson = μ>299,710.5 km/sec μ=299,...
