In the attached spreadsheet, you are given homework grades of 25 students. Sheet 1 (hw1) stores the first homework grades, Sheet 2 (hw2) is the second homework grades and so on. Use either xlsread() or readmatrix() to import the given data into Matlab. Once you have the data in Matlab; • 1- Create separate arrays for each homework, name them as hw1, hw2, hw3, hw4, hw5 • 2- Create an average grade array named hwAvg. Store the average homework grade in hwAvg using the below weights Homework 1, 2: each 15% Homework 3, 4 : 20% Homework 5: 30% • 3- Create an array named letterGrade to store letter grades, this will be an array of strings. • 4- Preallocate the letterGrade array. Make sure it has the same length as hwAvg array. • 5- Assign letter grades from hwAvg array using the grading policy shown below 100 - 90 : A <90 - 80 : B <80 - 70 : C <70 - 60 : D <60 :F It is recommended that you download the file, see what it looks like, figure the steps out on Matlab software before you start solving on Grader.

![Assign letter grades
O solutions submitted (max: 1)
In the attached spreadsheet, you are given homework grades of 25 students.
Sheet 1 (hw1) stores the first homework grades, Sheet 2 (hw2) is the second homework grades and so on.
Use either xlsread() or readmatrix() to import the given data into Matlab. Once you have the data in Matlab;
1- Create separate arrays for each homework, name them as hw1, hw2, hw3, hw4, hw5
2- Create an average grade array named hwAvg. Store the average homework grade in hwAvg using the below weights
Homework 1, 2: each 15%
Homework 3, 4 : 20%
Homework 5: 30%
3- Create an array named letterGrade to store letter grades, this will be an array of strings.
• 4- Preallocate the letterGrade array. Make sure it has the same length as hwAvg array.
5- Assign letter grades from hwAvg array using the grading policy shown below
100 - 90 : A
<90 - 80 : B
<80 - 70:C
<70 - 60 : D
<60
:F
It is recommended that you download the file, see what it looks like, figure the steps out on Matlab software before you start solving on Grader.
