Answer to Question 1

D
The t-test measures the significance of the effect of the individual independent variables, and the p value (for that same variable) indicates how strong the evidence is in favor of the coefficient's not being zero in the population based on one's sample data.

Answer to Question 2

Total quality management is a business strategy that emphasizes market-driven quality as a top priority. Research is important at each of the following stages:
(1) Commitment and exploration stage - exploratory study to determine the quality of customer wants, discover customer problems, and identify the importance of specific attributes. Exploratory study is also useful to determine employees' awareness of quality standards for their job.
(2) Benchmarking stage - conduct a study to measure overall satisfaction and quality rating of specific attributes and to measure employees' actual performance and perceptions about performance.
(3) Initial quality improvement stage - tracking wave 1 measures trends in satisfaction and quality ratings and comparing what is actually happening with what should be happening. Research is also conducted to establish whether the company is conforming to its quality standards.
(4) Continuous quality improvement stage - tracking wave 2 measures trends in satisfaction and quality ratings and trends in quality improvement.
