Hypothesis Testing - T-Tests in R Studio: One Sample Mean with raw data | One-Tailed & Two-Tailed

How to perform t.test for one-sample mean in R! We'll use the built-in "cars" dataset to explore: • Hypothesis testing: Learn how to test if the average speed in the dataset differs from a specific value. • Confidence intervals: Discover how to interpret confidence intervals and draw conclusions about the true mean. • Two-tailed vs. one-tailed tests: Understand the difference and when to use each approach. • Significance levels: Learn how p-values help you decide whether to reject the null hypothesis.
