Description:
Dive into a comprehensive 50-minute video tutorial on the Central Limit Theorem and its application in statistical analysis using Excel. Build a Sampling Distribution of Sample Means (Xbar) to understand this powerful statistical concept. Calculate mean and standard deviation for the sampling distribution, and explore how the theorem is used in business decision-making through hypothesis testing and confidence intervals. Learn to utilize Excel functions like NORM.DIST, NORM.S.DIST, NORM.S.INV, and T.INV while examining z and t distributions as models for the Sampling Distribution of Sample Means. Apply these concepts to real-world examples, including insurance policy pricing and computer printer cartridge manufacturing. Download accompanying Excel and PDF files for hands-on practice and reference.
