Explanation / Answer

a)here as data is for sample threfore we can not calculate population mean

also some value which are 100+ are not suitable for calculation therefore

measure of center that can be calulated"

20% trimmed mean

sample median

b)

putting data in ascending order

removing 20% va;lues from top and bottom:

20% trimmed mean =396/6 =66

and sample median =(n+1)/2 th value =(57+78)/2 =67.5

( put NONE in rest of given options)
