The quality manager believes there may be a relationship between the experience

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 which passed and failed inspection was determined based on three inspector experience levels. The results are shown in the following table. Decision Pass Fail Low ( < 2 years) Experience Level Medium (2-8 years) 285 43 High (> 8 years) 102 26 153 15 a. Select the competing hypotheses to determine whether the inspector pass/fail decision depends on experience level. Ho: Inspector pass/fail decision and experience level are independent; HA: Inspector pass/fail decision and experience level are dependent. Ho: Inspector pass/fail decision and experience level are dependent; HA: Inspector pass/fail decision and experience level are independent. 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.) Answer is complete but not entirely correct. Test statistic 6.877 x
