This row will store the "Test Averages." Store the value "Test Averages" in 'students' array. (Example - students[4] = "Test Averages": ) Update the displayGrades method to show the last row/Test Averages (highlighted in yellow above). Add a method "computeTestAverage;" which computes and stores the test average for each test (highlighted in yellow above). Run your program and show that the all the above has been updated and/or added. Method Name Description 1 compute TestAverages NEW METHOD computes and stores the test average for each test, in the last row of the grades 2D array Chialiohted in vellow above) MODIFY Lab 13 and add the following basic If needed, change the declaration of both arrays to include an extra row. will store the "Test Averages" Store the value "Test Averages" in "stadents' array. (Example - students[4] - "Test Averages": Update the displayGradus method to show the last row/Test Averages (highlighted in yellow above), Add a method "compute TestAverages" which computes and stores the test average for each test (highlighted in yellow above).
