Statistica Inferenziale 04 - Esercizi svolti sugli intervalli di confidenza (media e proporzione)

In this video, we'll work through two exercises on calculating a confidence interval to estimate a quantitative characteristic (in the case of the mean) or a qualitative characteristic (in the case of a proportion) using an interval. By the end of the video, you'll have put into practice the concepts and formulas learned in theory for calculating confidence intervals, also exploring the relationship between precision (interval width) and certainty (level of confidence) of the information. ______________________________________________________________ 🙏Thanks to Dr. FerruX for his valuable advice and support. / @DocFerruX Follow his channel for math content dedicated to the early years of high school. ______________________________________________________________ #️⃣Hashtag: #school #teaching #learning #studying #teaching #learning #understanding #Mathematics #probability #combinatorial calculus #calculus #maths #mathematics #math #numerical #factorial #classicalprobability #incompatibleevents #favorablecases #probabilitytheory #probabilitydistribution #randomvariables #statistics #statisticalmethods ______________________________________________________________ INDEX 00:00 Intro and channel objective 01:02 Exercise 1 (estimating the mean) - Exercise text 01:28 Ex 1 - part 1 - Estimating the standard deviation of the sample mean 03:21 Ex 1 - part 2 - 95% confidence interval for the mean 06:16 Ex 1 - Part 3 - Relationship between Confidence Level and Interval Width 07:57 Ex 1 - Part 4 - Finding the Sample Size to Observe Given the Confidence Level and Interval Width 10:55 Exercise 2 (Estimating the Proportion) - Exercise Text 11:21 Ex 2 - Part 1 - Point Estimation of the Proportion and the Standard Deviation of the Sample Frequency 13:33 Ex 2 - Part 2 - Confidence Intervals for the Proportion at the 99% and 90% Confidence Levels 17:40 Ex 2 - Part 3 - Finding the Sample Size to Observe Given the Confidence Level and Interval Width (Conservative Approach) 21:28 Outro
