#NUMPY CHECKPOINT #Create a numpy array called "grades" that contains the following grades: [85, 90, 88, 92, 95, 80, 75, 98, 89, 83] import numpy as np grades = np.array([85, 90, 88, 92, 95, 80, 75, 98, 89, 83])

Print the array

print("Grades:", grades) #instructions:

#grades_analysis.py: import numpy as np

Create the "grades" array

grades = np.array([85, 90, 88, 92, 95, 80, 75, 98, 89, 83])

Calculate mean, median, and standard deviation

mean_grade = np.mean(grades) median_grade = np.median(grades) std_deviation = np.std(grades)

Print the results

print("Grades:", grades) print("Mean:", mean_grade) print("Median:", median_grade) print("Standard Deviation:", std_deviation)

import numpy as np

Create the "grades" array

grades = np.array([85, 90, 88, 92, 95, 80, 75, 98, 89, 83])

Calculate maximum and minimum grades

max_grade = np.max(grades) min_grade = np.min(grades)

Sort grades in ascending order

sorted_grades = np.sort(grades)

Find the index of the highest grade

index_of_highest_grade = np.argmax(grades)

Count the number of students who scored above 90

num_students_above_90 = np.sum(grades > 90)

Print the results

print("Grades:", grades) print("Maximum Grade:", max_grade) print("Minimum Grade:", min_grade) print("Sorted Grades:", sorted_grades) print("Index of Highest Grade:", index_of_highest_grade) print("Number of Students Above 90:", num_students_above_90)

Create the "grades" array

grades = np.array([85, 90, 88, 92, 95, 80, 75, 98, 89, 83])

Calculate the percentage of students who scored above 90

percentage_above_90 = np.mean(grades > 90) * 100

Calculate the percentage of students who scored below 75

percentage_below_75 = np.mean(grades < 75) * 100

Extract all grades above 90 into a new array "high_performers"

high_performers = grades[grades > 90]

Create a new array "passing_grades" containing grades above 75

passing_grades = grades[grades > 75]

Print the results

print("Grades:", grades) print("Percentage of Students Above 90:", percentage_above_90, "%") print("Percentage of Students Below 75:", percentage_below_75, "%") print("High Performers:", high_performers) print("Passing Grades:", passing_grades)
