A: Assumptions

In this problem data were collected for variable(s) from sample(s).
Which of the following assumptions must be checked?
Check all that apply.
- All observed counts are at least 5
- Population standard deviations are known
- All sample sizes are at least 30
- N >= 20n
- All expected counts are less than 5
- All observed counts are less than 5
- N < 20n
- Population standard deviations are unknown
- All expected counts are at least 5

Check the assumptions:

1. Enter the list of expected values (round values to 2 decimal places):

- Are all of the expected values greater than or equal to 5?

2. No N is given, we will assume N

N: Name the test

The conditions are met to use a .

T: Test Statistic

The formula set up of the first and last term of the test statistic are as follows:

Round initial values to 2 decimal places:

χ2=Σ(O−E)2Eχ2=Σ(O-E)2E = ( - )^2^2/ + ... + ( - )^2^2/

Final answer from technology rounded to 2 decimal places:

χ2χ2 =

O: Obtain the P-value

Report the final answer to 4 decimal places.

It is possible when rounded that a p-value is 0.0000

P-value =

M: Make a decision

Since the p-value , we .

S: State a conclustion

There significant evidence to conclude that the distribution of for the stated distribution.
