Question

SOMEONE PLEASE explain to me theoretical probability without using dice or a coin

Answer 1

what about using a spinner?

Answer 2

hahahha! ok how about... how would it be applied if i had measurements (30)
if you dont use the data because its theoretical how would i apply it?

Answer 3

measurements mean nothing if they don't come with units attached
is that 30%?

Answer 4

well i have 30 measurements, 30 people measured their pinky, each put down the amount of centimeters...
i dont know how to answer theoretical questions about this data

Answer 5

any ideas?

Answer 6

what do you mean by theoretical questions?

Answer 7

ok so i did the empirical data work... you know... mean, standard deviation, quartiles... percentiles.. but when it comes to the theoretical work, i dont know what to do with it

Answer 8

i dont know...

Answer 9

can you show me what the question's asking? i'm sorry, I just don't get it.

Answer 10

i dont know...

Answer 11

ooooooooh, yeah I'm of no use here. I can't remember most stats :(

Answer 12

do you know anyone that may know this?

Answer 13

I think part 2 is the stuff she filled out

Answer 14

what do you mean?

Answer 15

Do you see in the directions
"use the theoretical distribution in part II" .
is there a part II given elsewhere?

Answer 16

Or is that all the information given, in which case that is part 2.

Answer 17

nope

Answer 18

let me check

Answer 19

i see no part 2

Answer 20

Maybe they are referring to the standard normal distribution, if we assume that the pinkies are distributed in a bell curve.

Answer 21

yes, ok so what do i do with that

Answer 22

I found this online.

It looks like they want you to graph the data using a histogram, then draw a smooth curve along the tops of the rectangles of the histogram. The shape of this curve will be your theoretical distribution .

Answer 23

Can I see your data for the 30 pinkies
