Pollsters want to test if an association exists between a person's profession and their political party. A random sample of 323 voters is polled, resulting in the data in the following table. Based on these results, is there enough evidence at the 0.05 level of significance to say that an association exists? Observed Sample of Voters Democrat Republican 39 36 40 22 19 29 146 Doctor Lawyer Teacher Farmer Laborer Total 40 38 14 46 177 Total 75 80 60 33 75 323 Copy Data Step 3 of 4: Compute the value of the test statistic. Round your answer to three decimal places, if necessary. (Note: If calculating by hand, be sure to use at least six decimal places in numbers for all intermediate calculations to ensure accuracy of the result.)
