Answer 1

Part 1. note the strength of correlation between pairs of the company's service elements.

Reson: The roof of a quality house shows the correlations among the different features which can also be the service elements for a firm.

Part 2. Internal Failure cost

Reason - they are internal because the defect has not flown to the customers.

Part 3. A Type I error has occurred which is the producer's risk.

Reason - We are rejecting a hypothesis that the part is defective where in fact it is defective. Such error cannot be made by the consumer and always comes from the producer.
