Скачать или смотреть One-Sample t-Test in R | Hypothesis Testing & p-Value Explained

Welcome back to the Probability & Statistics series! 📊
In this session, we dive into hypothesis testing using R Studio. We build our own one-sample t-test step by step, calculate the test statistic, critical values, and p-value, and then compare results with R’s built-in t.test() function.

🔎 What you’ll learn in this video:

How to enter data vectors in R

Calculating mean, standard deviation, and sample size

Computing the t-calculated value manually

Determining the rejection region & decision rule

Finding the p-value in R

Using R’s t.test() for confirmation

Plotting the normal & t-distributions in R

We use a real-life example about water contaminants to see how hypothesis testing works in practice. 🌍💧

👉 Stay tuned until the end where we also connect confidence intervals to hypothesis testing!
