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 628 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. Experience Level Medium Low (< 2 years) High (> 8 years) Decision (2-8 years) Pass 153 285 102 Fail 16 46 26 a. Select the competing hypotheses to determine whether the inspector pass/fail decision depends on experience level. O Ho: Inspector pass/fail decision and experience level are independent; HA: Inspector pass/fail decision and experience level are dependent. O 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.)

Name 3) The Tire Rack, an online distributor of tires and wheels, conducts extensive testing to provide customers with products that are right for their vehicle, driving style, and driving conditions. In addition, the Tire Rack maintains an independent customer survey to help drivers help each other by sharing their long-term tire experiences (The Tire Rack website, August 1, 2016). The following data shows survey results (one to 10 scale with 10 being the highest rating) for 18 high performance all season tires. The variable tread wear rates quickness of wear based on drivers expectations, the variability dry traction rates the grip of a tire on a dry road, the variable steering rates the tires steering responsiveness, and the variable buy again rates the driver's desire to purchase the same tire again.
