Scenario 1: Tutorial Attendance
Question: Does the mean tutorial attendance differ significantly between two groups of students attending different tutorial sessions?
group1_attendance = [18, 20, 22, 19, 21] # Tutorial attendance for group 1
group2_attendance = [16, 17, 15, 18, 19] # Tutorial attendance for group 2
Null Hypothesis (H0): There is no significant difference in the mean tutorial attendance between the two groups.
Alternative Hypothesis (H1): There is a significant difference in the mean tutorial attendance between the two groups.

Alternative Hypothesis (H1): There is a significant difference in the mean exam scores between the two groups.
Data:
group1_scores = [85, 90, 88, 82, 87] # Exam scores for group 1

'Job Satisfaction': ['Satisfied', 'Dissatisfied', 'Satisfied', 'Satisfied', 'Dissatisfied', 'Dissatisfied'], 'Years of Experience': ['0-5', '0-5', '6-10', '6-10', '11-15', '11-15']
}
df = pd.DataFrame(data)

Question: Is there a significant difference in the mean exam scores among three different classes?
Null Hypothesis (H0): There is no significant difference in the mean exam scores among the three classes.
Alternative Hypothesis (H1): There is a significant difference in the mean exam scores among the three classes.
Data:
Sample data of exam scores for three classes: import pandas as pd
# Sample data data = {
'Class A': [85, 90, 88, 82, 87],
'Class B': [79, 82, 83, 85, 81],
'Class C': [75, 78, 79, 83, 80]
}
df = pd.DataFrame(data)
