Hi
You MUST have a good calculator or an electronic spreadsheet to do these.
Why??  Because others will and will be able to do all these in minutes.
#7 After sorted, median is (middle-two/2) = {{{  highlight_green((32+41)/2)=36.5 }}}  (same applies to #13 and 14)
#13  Mean - 72, Median = 70, SD = 12.15(round off according to Instructions: 2 decimal places)
#14  Mean = 4.05, Median = 4. SD = 1.97 (again round off according to Instructions: 2 decimal places)
Used Sum(x-mean)/(n-1) for Variance and then sqrt(Variance) for SD
