Unknown Story
Storyboard Text
- Take note that the sample size for t-test is less than 30, so even if the first condition is met but the sample size is greater than or equal to 30, then it will fall on central limit theorem.
- In central limit theorem, you will use the formula for z-test but instead of population standard deviation you will use sample standard theorem
- No problem! Please do yourself a favor and rest.
- Wow! Now I already understand the lesson. Thank you!
- Oh, there are conditions you need to consider to help you determine the appropriate test statistics.
- Like what?
- That food looks tasty... woof woof...
- I'm confused about when I need to use the different test statistics.
- For example, we use the z-test if the population standard deviation is known and if the sample size is greater than or equal to 30.
- Plus, if population is normally distributed.
- That looks more yummy...
- Statistics? Hehe, not to brag but that was my favorite subject when I was in high school.
- Sure! I'm your guy. I just need to run some errands then I'll get back to you.
- Really? So you could help me then?
