Assignment title: Information
Guide on how to use a computer program to find p-value, you need to do this in the assignment
for ANOVA (see pages 1 and 2) and chi square (see pages 3 and 4)
For example of chi squared test of independence the assignment question is similar to
For ANOVA the assignment question is
You can use a webpage to do this for example

Note that I entered 3 because there are 3 groups click submit
You have a webpage were you can enter data
The computer output is
ANOVA: Results
The results of a ANOVA statistical test performed at 16:46 on 17-SEP-2013
Source of Sum of d.f. Mean F
Variation Squares Squares
between 1016. 2 508.0 9.181
error 498.0 9 55.33
total 1514. 11
The probability of this result, assuming the null hypothesis, is 0.0067
This lets you select the correct option
For the chi squared test stat question
Just find a webpage to do this for example you can use
http://www.quantpsy.org/chisq/chisq.htm
So enter numbers and click calculate
This gives you the p-value , you need to work out the appropriate conclusion.
The p-value is not less than 0.05 so you should not reject H0 so pick option d
