Confidence Intervals Practice Problem 1

[gloriousliyah]

When doing sample mean you should use a T interval

[GizmoHey]

Wait why do we have to use inverse Normal?

[thatomononyane]

I like how you assumed that we all have a calculator like that😪

[bkgirlmay]

um for of all you talking about that calculator. That's a standard calculator. You will probably need it in college for higher-level maths. It's called a TI-84.

Thank you very much! This was super helpful

[mpcmpc]

what if the sample was smaller than 30? what would happen

[aliyunura]

most of us don't have fancy calculators and even if we do they don't let them inside the exam class

[divinest]

isn't it 50 adults not 500 adults

[rubianimaz]

You lost me at why I need to state my statement

[rubianimaz]

No wonder my profesor doesn’t let me use a T-81 🥲
