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.
