Central Limit Theorem (CLT) | Statistical Inference | VTU Exam Problem | Part 3

🎓 In this video, we solve another important Central Limit Theorem (CLT) problem from VTU Mathematics-III (BCS301) – Module 4: Statistical Inference 2.

Question:
In a recent study reported on the Flurry Blog, the mean age of tablet users is 34 years. Suppose the standard deviation is 15 years. Take a sample of size n = 100.
Using the Central Limit Theorem, find the probability that the sample mean age is more than 30 years.

You’ll learn:
✅ Concept of Sampling Distribution of the Mean
✅ Application of Central Limit Theorem (CLT)
✅ Calculating Probability using Z-scores and Normal Distribution Table
✅ Step-by-step VTU exam-oriented explanation
