Neutrinos and photos are both created by fusion and both leave the Sun. The neutrinos reach the Sun's surface after about 3 seconds and the photons can take 100,000 years to reach the surface, which is why I said studying the neutrinos from the Sun tells us about fusion happening right now. Why do the particles take different times to cross the same distances?

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?
