The data on the annual total number of earthquakes in the magnitude range of 5.0 to 9.9 between the years 1970-2012 globally are available in the file "earthquake.txt" on blackboard. (a) Create an x-y plot of the year and number of earthquakes. (b) Use the filter function to find a weighted average of the earthquake data, over a 7 year period. (c) Plot the original data and the filtered data on the same graph. Label x-y axis and add a legend.
