When sample measurements falls inside the control limits, it means that: a. the process limits cannot be determined statistically. b. the process output exceeds the requirements. c. each unit manufactured is good enough to sell. d. the process output does not fulfill the requirements. e. if there is no other pattern in the samples, the process is in control.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
