Statistics Grades: The statistics grades in the fall semester had mean of 65. The SRS were taken from different statistics groups (A, B, C and D) considering that the total number of students that took part on the exam was 110. Assuming that the change in the grades has a normal distribution with standard deviation σ= 10, We computed a 90% confidence interval of the mean change in score μ in the population of all statistics students. A) Find a...

Develop an interactive program to assist a Philosophy professor in reporting students’ grades for his PHIL-224.N1 to the Office of Registrar at the end of the semester. Display an introductory paragraph for the user then prompt the user to enter a student record (student ID number and five exam-scores – all on one line). The scores will be in the range of 0-100. The sentinel value of -1 will be used to mark the end of data. The instructor has...

Student stress at final exam time comes partly from the
uncertainty of grades and the consequences of those grades. Can
knowledge of a midterm grade be used to predict a final exam grade?
A random sample of 200 BCOM students from recent years was taken
and their percentage grades on assignments, midterm exam, and final
exam were recorded. Let’s examine the ability of midterm and
assignment grades to predict final exam grades.

Using C programming For this project, you have been tasked to read a text file with student grades and perform several operations with them. First, you must read the file, loading the student records. Each record (line) contains the student’s identification number and then four of the student’s numerical test grades. Your application should find the average of the four grades and insert them into the same array as the id number and four grades. I suggest using a 5th...
