Ch 10.1 Lesson

How can we can assume our samples are from a normally distributed population when we do not know?

• Using the central limit theorem

  𝑛1 ≥ 30 and  𝑛2 ≥ 30

• we cant

• 𝑛1 ≥ 30 or  𝑛2 ≥ 30

• 𝑛1 < 30 and  𝑛2 < 30

True or False: u1 - u2 is always set to 0 and you do not have to worry about that part of the formula.

• True

• False

True or False: s2 stands for sample standard deviation.

• True

• False
