The average monthly precipitation (in.) for Boston and Seattle during 2012 are given in the vectors below

Q: The average monthly precipitation (in.) for Boston and Seattle during 2012 are given in the vectors below (data from the U.S. National Oceanic and Atmospheric Administration) BOS = [2.67 1.00 1.21 3.09 3.43 4.71 3.88 3.08 4.10 2.62 1.01 5.93] SEA = [6.83 3.63 7.20 2.68 2.05 2.96 1.04 0.00 0.03 6.71 8.28 6.85] Where the elements in the vectors are in the order of the months (January, February, etc.) Write your program to answer the following: (a) Calculate the total precipitation for the year and monthly average precipitation in each city. Do NOT use MATLAB's built-in functions sum and mean. (b) How many months was the precipitation above the average in each city? (c) How many months, and on which months, was the precipitation in Boston lower than the precipitation in Seattle?
