A program at SF State is concerned about their graduation rates. Every year they enroll 400 junior-level students, and they’ve been tracking the percent who manage to finish (graduate from) the program in a timely manner. Below are the data for the past 8 years. Express all calculations to 3 significant figures: ie. 12.3% or 0.123 (also 3-decimal spaces).

year	2000	2001	2002	2003	2004	2005	2006	2007
ontime grads	230	215	250	225	245	220	235	205

Calculate the proportion of the class that graduates each year.
What kind of control chart should be used in this situation? pChart Justify Why.
Compute the 3 sigma control limits

Are we in control, give the control
