T distribution | t-Test | Part 4

📘 Problem: The nine items of a sample have the following values: 45, 47, 50, 52, 48, 47, 49, 53, 51. Does the mean of these values differ significantly from the assumed mean of 47.5 at 5% level of significance? 🎯 Concept Covered: 👉 Hypothesis testing for population mean using Student’s t-test 👉 Calculation of sample mean and standard deviation 👉 Finding calculated t-value and comparing with t-table value 👉 Decision on acceptance or rejection of null hypothesis 👉 Interpretation of results based on 5% significance level 📚 Topic: Statistical Inference – Hypothesis Testing (t-test for Mean) 🎓 Applicable For: VTU | Engineering Mathematics-III | Module 4 T distribution & t-Test Explained | Statistical Inference: https://www.youtube.com/playlist?list=PLM9RnGtTy9_8-OzGo9uc-_GTADOoEPoM- 🎥 Playlist Videos: 1️⃣ T Distribution | t-Test for Mean Height | Part 1 🔗 https://youtu.be/bFxmakY69c0 2️⃣ T Distribution | t-Test for Mean Height | Part 2 🔗 https://youtu.be/ar_J3aEuXt4 3️⃣ T Distribution | t-Test | Part 3 🔗 https://youtu.be/ZX444LoOtkk 4️⃣ T Distribution | t-Test | Part 4 🔗 https://youtu.be/xtX8in_sDVw 5️⃣ T Distribution | t-Test | Part 5 🔗 https://youtu.be/mpNdqcx9NpM 💎 Support Us: Join our channel and get access to exclusive perks 👇 🔗 https://www.youtube.com/channel/UC_OTtwh8_-q-bA7DoS--syg/join #tTest #HypothesisTesting #StatisticalInference #EngineeringMathematics3 #VTUMaths #MathsMadeSimple #VTU #MathsForEngineers #tDistribution #SmallSampleTest #StatisticsForEngineers #MathsTutorial #VTUExamPreparation
