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...

Use the Grouped Distribution method for the following exercise (see Self-Test 2-4 for detailed instructions), rounding each answer to the nearest whole number. Using the frequency distribution below (scores on a statistics exam taken by 80 students), determine:ion 1 of the preliminary test (scores on a statistics exam taken by 80 students), determine: 68 84 75 82 68 90 62 88 76 93 73 79 88 73 60 93 71 59 85 75 61 65 75 87 74 62 95...

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...

While the following simple random samples of Statistics test scores both come from populations that are normally distributed, we do not know the standard deviation of the populations. The first simple random sample is drawn from the scores on Exam 1 for an on-line Statistics class and the second simple random sample is drawn from the scores on the exact same Exam 1 for an on-land (traditional) Statistics class. Using the null hypothesis that there is no difference in the...

The purpose of the testing was to assess the extent to which their scores improved as a result of the course work they had done during the 3 months. Their scores on the two tests (each out of 100) are as follows: First Test Second Test 72 82 65 74 69 78 80 68...

Write the definition of the class Tests such that an object of this class can store a student's first name, last name, five test scores, average test score, and grade. (Use an array to store the test scores.) Add constructors and methods to manipulate data stored in an object. Among other things, your class must contain methods to calculate test averages, return test averages, calculate grades, return grades, and modify individual test scores. The method toString must return test data...
