The quality manager believes there may be a relationship between the experience level of an inspector and whether a product passes or fails inspection. Inspection records were reviewed for 630 units of a particular product, and the number of units that passed and failed inspection was determined based on three inspector experience levels. The results are shown in the following table. (Table is the picture) b. Calculate the value of the test statistic. (Round the intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.) Test Statistic = c. Find the p-value. 0.01 ≤ p-value < 0.025 p-value < 0.01 0.025 ≤ p-value < 0.05 p-value ≥ 0.10 0.05 ≤ p-value < 0.10
