1. Bar and Pie Charts for number of siblings in a sample of 500 students.
2. Bar and Pie Charts for the transportation modes of 200 workers.
3. Frequency Table for Toyota cars sold in September based on daily data.
4. Frequency Table and Histogram based on student exam scores.
5. Frequency Table and Histogram for delivery times in days.
6. Frequency Distribution for weights of 80 people, with questions about percentages of certain weight ranges.

Part II: Measures of Central Tendency and Dispersion

1. Mean, Median, and Mode for football team goals.
2. Mean, Median, and Mode for a set of 9 values.
3. Calculation of Q1 (first quartile), D5 (median decile), and P75 (75th percentile) from exam scores.
4. Mean, Mode, Median, and Quartiles for ages of football club members.
5. Mean Deviation, Standard Deviation, and Variance for a given data set.
6. Weekly Complaint Statistics for customer service quality.

Part III: Probability Problems

1. Dice problems involving sums and conditions.
2. Probabilities from survey data.
3. Conditional probabilities for defects in textiles.
4. Probabilities from survey data based on residence.

Part IV: Distribution and Binomial Problems

1. Distribution of Defective Computers.
2. Binomial Probability for vehicle sales with airbags.
3. Cumulative Distribution of the binomial problem.
4. Binomial Problem for component survival in crash tests.
5. Binomial Probability of recovery from a rare disease.

Expansion Questions:

1. How would you create a bar chart for the data on siblings?
2. What is the method to calculate the median in grouped data?
3. How do you find conditional probability in a two-dice problem?
4. How is a frequency histogram different from a bar chart?
5. What steps are involved in calculating standard deviation?

Tip:

When solving probability problems, always check if events are independent or dependent—this changes how you calculate their probabilities!
