# This section contains test cases, which will execute your functions
# and print out the results. These tests are "protected" (by indentation) within 
# an if statement, which will prevent them from running on the Gradescope server.
# You must write all of your test cases within this indented block.
if __name__ == '__main__':

    # make sure all of your test cases are indented by 1 tab, following the example below.
    # declare several variables with which to test the functions
    a = 8
    b = 9
    c = 10
    d = 9
    e = 8

    # We make a function call to the `calc_sum` function,
    # and assign the result into a variable called `sum_of_obs`
    sum_of_obs = calc_sum(a, b, c, d, e) 
    # now we print out this variable
    print("The sum of observations is:", sum_of_obs)

    # TO DO: you need to call each of your other functions below, 
    # and verify the results by printing them out
    
    




## DO NOT WRITE ANY TEST CASES IN THE GLOBAL SCOPE (i.e., at the left margin of the file).
