Question
Better light After his first attempt to determine the speed
of light (described in Exercise 21), Michelson conducted
an “improved” experiment. In 1897 he reported results of
100 trials with a mean of 852.4 and a standard deviation
of 79.0.
a) What is the standard error of the mean for these data?
b) Without computing it, how would you expect a 95%
confidence interval for the second experiment to differ
from the confidence interval for the first? Note at least

the true speed of light is 299,710.5 km>sec,
corresponding to a value of 710.5 for Michelson’s1897 measurements. What does this indicate about
