Previous question is not given.

I'll assume that the test statistic is calculated as thus;

(Expected Proportion - Actual Proportion) * 100

The function goes as follows.

#function is written in Python Programming Language.

def test _statistic (expected, actual)

return 100 * abs (expected - actual)

The first line of the program defines the function test_statistic along with two parameters.

The parameters are expected and actual.

expected represents expected proportion whole actual represents actual proportion

The second line calculates the value of the test_statistic.

First the absolute value is calculated to remove all negative signs. Since the results is needed in percentage, it's then multiplied by 100.
