we know that
1) Prior to the missing test
a) mean=[82+100+96+90+91]/5=459/5------> 91.8
b) median
82,90,91,96,100-------> the median is 91
2) After introducing the 0 test score
a) mean=[82+100+96+90+91+0]/6=459/6------> 76.5
b) median
0,82,90,91,96,100-------> the median is [90+91]/2-----> 90.5
therefore
a) Following the addition of the 0 test score, utilizing the mean is the most valid measure of center for the data-------> is true
b) The inclusion of the 0 test score would influence the mean-----> is true
c) The median would be the more suitable measure of center after adding the 0 test score-----> is false
d) Eva’s median score prior to the missed test was 96-----> is false
e) Eva’s median score before the missed test was 91------ is true
f) Eva’s average score before the missed test was 91.8-----> is true
