The production manager in an automobileplant is concerned with the number of cars that do not pass the final quality control inspection. In the last two hours he noted that in a sample of 120 cars only 92 were acceptable. The lower and upper limit of a 95% confidence interval for the true percentage of all cars that would not pass the final quality control inspection would be:

	a.	0.227, 0.233
	b.	0.695, 0.845
	c.	0.155, 0.305
	d.	0.167, 0.293
	e.	0.707, 0.833
