The population full-time equivalent number of students (FTES) at Lake Tahoe Community College 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 1,585 1,690 1,735 1,935 2,021 1,890 Calculate the mean, median, standard deviation, the first quartile, the third quartile and the IQR. Round to one decimal place.

Answer 1

The mean of the set of numbers that are given in this situation regarding the population will be 1809.33.

How to solve the mean

The mean of the numbers will be:

= (1,585 + 1,690 + 1,735 + 1,935 + 2,021 + 1,890) / 6

= 1809.33

The median of the numbers will be:

= (1735 + 1890) / 2

= 1812.50

Also, from the complete question, the first quartile will be 1690 and the third quartile is 1935.
