Goals of this lesson:

Conduct a two-sided t test for comparing two population means

t.test()

 

Instructions

• Watch the following video:

Lesson 6 Two-sample t test (two-sided)

Remarks:

• We will use the t.test () command to run two-sided tests only.
• Even though we only want to find the P-value, R will automatically generate BOTH the P-value and the confidence interval every time we run t.test().
• The relationship between a confidence interval and a two-sided hypothesis test will NOT be covered in the final exam.
