Answer 9

This is a `Chi-Square Goodness of Fit` type of problem. I'm assuming since the level of significance isn't given, we assume that alpha = 0.05 by default.

okay, what do i need to do to complete the question? @jim_thompson5910

Answer 11

are you familiar with `Chi-Square Goodness of Fit` test? or is this the first time you've heard of it?

Answer 12

if it's the first time, then I recommend reading this article

let me know if it helps or not

Answer 13

could you walk me through the steps of what to do please? i learn better by example @jim_thompson5910

Answer 14

alright, so the table of values is the given information

this information is the `observed values` denoted O (upper case letter 'oh')

contrast this with the expected values E

any guesses of what the expected values should be if each outcome is equally likely?

Answer 15

hint: try to find the probability of landing in one slot then multiply that with the total

Answer 16

So yes first of all assuming each is equally likely, on 90 spins what would you expect to get for each of the six types.
