Program 3: Create a Histogram for number of hours students spent studying per week using Python Number:
[5, 7, 8, 10, 12, 14, 15, 16, 18, 20, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24]

This example takes number of hours per week that students spend in studying. To create a histogram from the given
data, we must first organise it into intervals. These intervals are frequently referred to as logical ranges or bins.
Code:
import seaborn as sns

import matplotlib.pyplot as plt

# List of hours students spend studying per week
study_hours = [5, 7, 8, 10, 12, 14, 15, 16, 18, 20, 9, 11, 13, 15, 17, 19, 21, 23,
25, 27,6, 8, 10, 12, 14, 16, 18, 20, 22, 24]
# Create histogram

sns.histplot(study_hours, bins=6, color='skyblue')
# Add titles and labels
plt.title("Histogram of Study Hours per Week")
plt.xlabel("Hours Spent Studying")

plt.ylabel("Number of Students")
# Display the plot
plt.show()
