ufacturer considers his production process to be out of control when defects exceed 4%. In a random sample of 146 items, the defect rate is 8.3% but the manager claims that this is only a sample fluctuation and production is not really out of control. At the 5% level of significance, use the p-value method to test the manager's claim. Enter the p-value. (Round your answer to nearest thousandth.) When using tables to find a tight range for the p-value, enter one of the boundaries of the interval (not 0 or 1) found using the tables.
