1. Using the percent passing developmental courses in shown in the table for your campus in Fall 2009, what is the sampling distribution model of the percent passing developmental courses for your campus in Fall 2009? That is, what is the mean ( )and the standard deviation SD ( )? See page 460 or 463 in your textbook.
2. Using the 68-95-99.7 rule, to describe the sampling distribution for the proportion of students passing developmental courses for your campus in Fall 2009. Provide the percentages between which we would expect to see 68% of the sampling distribution, 95% of the sampling distribution and 99.7% of the sampling distribution.
3. In Fall 2010, what % of students passed developmental courses at the campus you selected? Is that percentage unusual based on the sampling distribution you determined for Fall 2009? Is the percentage unusually high or low?
