I need detailed images, witout using AI, do by hand , and make sure ecplain everything

Scenario: A group of 40 individuals recorded the amount of time (in hours) they spent on various
activities in a day. The activities include sleeping, working, exercising, leisure, and other tasks. The
data collected for "leisure" time is as follows:
[2, 3, 1.5, 4, 2.5, 3, 2, 5, 1, 3.5, 2, 4.5, 3, 2.5, 1, 4, 3, 2, 5, 3.5, 2, 4, 3, 2.5, 1.5,
4, 3, 2, 5, 3.5, 2, 4, 3, 2.5, 1, 4.5, 3, 2, 5]
Tasks:
1. Create a Histogram:
• Objective: Illustrate the distribution of leisure time among individuals.
• Instructions:
• Choose appropriate intervals (e.g., 1-2 hours, 2-3 hours, etc.).
.
Tally the number of individuals in each interval.
Plot the histogram accordingly.
2. Create a Bar Chart:
• Objective: Compare the frequency of specific leisure time durations.
. Instructions:
• Decide on categories (e.g., 1-2 hours, 2-3 hours, etc.).
•
Create bars representing the count of individuals in each category.
Ensure the chart is well-labeled and easy to interpret.
3. Analysis Questions:
• a. Identify the most common range of leisure time.
•
b. Calculate the average leisure time and discuss how it relates to the histogram.
•
•
c. Determine the probability that a randomly selected individual spends more than 4 hours
on leisure activities.
d. Discuss any trends or patterns observable from the visualizations and suggest reasons for
these patterns.
