Use the following information to answer the next nine exercises: the population parameters below describe the full-time equivalent number of students (ftes) each year at lake tahoe community college from 1976–1977 through 2004–2005.

• μ = 1000 ftes
• median = 1,014 ftes
• σ = 474 ftes
• first quartile = 528.5 ftes
• third quartile = 1,447.5 ftes
• n = 29 years

additional information: the population ftes for 2005—2006 through 2010—2011 was given in an updated report. the data are reported here.

year: 2005-06 2006-07 2007-08 2008-09 2009-10 2010-11
total ftes: 1585 1690 1735 1935 2021 1890

compare the iqr for the ftes for 1976—77 through 2004—2005 with the iqr for the ftes for 2005-2006 through 2010— 2011. why do you suppose the iqrs are so different?
