1. The Chair of the Operations Management Department at Quality University wants to construct a p-chart for determining whether the four faculty teaching the basic P/OM course are under control with regard to the number of students who fail the course. Accordingly, he sampled 100 final grades from last year for each instructor, with the following results:

   Instructor	Number of Failures
   A	13
   B	0
   C	11
   D	16

   What are the .95 (5% risk of Type I error) upper and lower control limits for the p-chart?

   		.95 and .05
   		.13 and .07
   		.1588 and .0412
   		.16 and .04
   		.1774 and .0226
