A 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 620 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.

Decision	Experience Level
Low (< 2 years)	Medium (2-8 years)	High (> 8 years)
Pass	151	287	101
Fail	14	41	26

a.Select the competing hypotheses to determine whether the inspector pass/fail decision depends on experience level.

b.Calculate the value of the test statistic.

Note: Round the intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.

c.Find thep-value.
