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.

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...
