The following table gives the total caseload in millions in

The following table gives the total caseload (in millions) in a state\'s courts from 2004 through 2009.

Find the mean of the total caseload for the state\'s courts from 2004 through 2009. (Round your answer to two decimal places.)
4.43 million cases - CORRECT

What is the standard deviation for these data? (Round your answer to two decimal places.)
? million cases

Year	2004	2005	2006	2007	2008	2009
Cases	4.8	4.9	4.2	4.4	4.1	4.2

Solution

Dear Student Thank you for using Chegg !! Given Sno Case Load Cases (In Million) Mean = Sum Of Cases / Count of Cases Deflection from Mean Square of deflection Variation Standard Deviation 1 2004 4.8 4.433333333 0.366666667 0.134444444 0.095556 0.309120617 2 2005 4.9 0.466666667 0.217777778 3 2006 4.2 -0.233333333 0.054444444 4 2007 4.4 -0.033333333 0.001111111 5 2008 4.1 -0.333333333 0.111111111 6 2009 4.2 -0.233333333 0.054444444 Mean = Sum of Values / No of Values Variation = Sum of squares of defelection from mean / No of Values Standard Deviation = Square root of variation
