Statistics

Information provide by the bureau of labor statistics can be used to show that the mean number of monthly works in 2003 was x?= 10190 and the standard deviation for the number of monthly workers was s= 112.6. (take these values as given)

A. Using Chebychev's theorom, construct an interval in which you expect at least 75% of all vallues for workers per month for 2003.

B. If you have reason to believe that the data on number of monthly workers would produce a histogram that is roughly bell curve shaped, how would this change your description of the interval you calculated in part A?
