As a result of his observations, ole roemer concluded that eclipses of io by jupiter were delayed by 22 min during a six–month period as the earth moved from the point in its orbit where it is closest to jupiter to the diametrically opposite point where it is farthest from jupiter. using the value 1.50 108 km as the average radius of the earth's orbit around the sun, calculate the speed of light from these data.

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
