Chapter 11.2, Problem 55E

To determine

To find: The degree of freedom for the provided test.

Answer to Problem 55E

The degree of freedom is 4.

Explanation of Solution

Given:

The table is:

	Female	Male
Almost no chance	119	103
Same chance	150	171
50-50 chance	447	512
A good chance	735	710
Almost certain	1174	756

Formula used:

The formula to compute the degree of freedom is:

  $\text{Degree of freedom = Number of categories -1}$

Calculation:

The degree of freedom is computed as:

  $\begin{array}{c}\text{Degree of freedom = Number of categories -1}\\ \text{=5-1}\\ \text{=4}\end{array}$

Hence, the correct option is (a).
