What is the total value of the test statistic?  Express the answer without rounding, since the answer is a terminating decimal.  As a courtesy, here is the expanded distribution with observed and expected values.

Copy the table into a spreadsheet to perform the following calculations:

1. Subtract the expected value from each corresponding observed value:


2. Square each difference:


3. Divide each squared difference by its expected value:


4. Sum all those quotients:
