CSC888 has 4 people. Each person needs to take 3 tests. Create a 4-by-3 two-dimensional array to store the test scores. Ask the user to enter test scores one at a time to populate this array. Once the whole array is filled, do the following two things.
(1) For each student, display her test scores and the average of the three tests.
(2) For each test, display student scores and the average of the four students.
The following shows a test run of the program:
Enter test scores of student #1
Test #1: 95
Test #2: 92
Test #3: 88
Enter test scores of student #2
Test #1: 87
Test #2: 100
Test #3: 82
Enter test scores of student #3
Test #1: 76
Test #2: 74
Test #3: 81
Enter test scores of student #4
Test #1: 98
Test #2: 97
Test #3: 93

Average: 91.6666666666667
Student #2

C++: Create a grade book program that includes a class of up to 20 students each with 5 test grades (4 tests plus a Final). The sample gradebook input file (CSCI1306.txt) is attached. The students’ grades should be kept in an array. Once all students and their test scores are read in, calculate each student’s average (4 tests plus Final counts double) and letter grade for the class. The output of this program is a tabular grade report that is...

PLEASE SHOW ME HOW TO DO THIS.... For the Excel Data Set please find and report for Test 1 and Test 2 the Mean, SD, and the tolerance levels for both for which there would be any outliers (i.e., the value for which a score must be less than to be consider an outlier and the value for which a number must greater than to be considered an outlier.
