Changing into the Solve aplet we can enter a formula which will allow
us to calculate values from the Chi
2
distribution using the UTPC function.
With a 3x2 contingency table the number of degrees of freedom are 2.

To find the critical
0.05
value, we enter values of 2 for D (the degrees of
freedom) and 0.05 for
P (the probability) and then move the highlight to
V (the value) and press . As it turns out, the required critical
value is 5.99 and so we would accept the null hypothesis and conclude
no relationship.
