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). His measurements are given in table #7.3.6. Is there evidence to show that Michelson’s data is different from Stigler’s value of the speed of light? Test at the 5% level.

We have given the sample data of 23 observations.
From the given data we get -
x bar = 299756.2174 , s = 107.1146 , n = 23
Hope this will help you. Thank you :)

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 22 trials with a mean of 756.22 and a standard deviation of 112.75. a) Find a 90% 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...
please help! 2. Leon Foucault (French physicist) measured the speed of light with a rotating mirror in 1862. Albert Michelson (American physicist) refined Foucault's method to make a series of measurements over many years. His 1924 measurement was a major advance. The drawing shown below is a simplified description. SOURCE MIRRO TE LESCOPE OCTAGON AL RO ATING MIRROR Image of the source is seen in the telescope. When the mirror starts rotating, the image disappears. When the speed of rotation...
Between 1878-1879, Albert Michelson conducted experiments to measure the speed of light. He sent a beam of light from a revolving mirror to a stationary mirror far away and back again. Assuming that in one of his experiments, the distance from the revolving mirror to the stationary mirror was 15.0 km, then the time interval between the light leaving and returning to the revolving mirror would have been:

DATA 4.1 Does Light at Night Affect Weight Gain? Numerous studies have shown that exposure to light at night is harmful to human health. A recent study? examines the effect of light at night on body mass gain in mice. Eighteen mice were randomly assigned to one of two groups: the Dark group had a normal light/dark cycle with darkness at night and the Light group had a dim light on at night, equivalent to having a television set on...
