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...

Two placement exams are
available that students can take to determine which math class they
should begin with in their freshman year. It is believed that there
is no difference in the mean scores that would be received for the
two tests. To test this using a 0.05 level of significance, a
randomly selected group of students took both tests and had their
scores recorded. The following data were obtained: Student Test A
