The following sample data reflect shipments received by a large firm from three different vendors and the quality of those shipments. (You may find it useful to reference the appropriate table: chi-square table or F table) Vendor Defective Acceptable 119 1 32 25 26 76 207 a. Select the competing hypotheses to determine whether quality is associated with the source of the shipments. O Hạ: Quality and source of shipment (vendor) are independent.; Ha: Quality and source of shipment (vendor) are dependent. O Hạ: Quality and source of shipment (vendor) are dependent.; Ha: Quality and source of shipment (vendor) are independent. b-1. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.) Test statistic
