Eva earned the following test scores in science: 82, 100, 96, 90, 91 ms. wade entered the next score as 0 because eva was absent on test day and hadn’t had a chance to make up the test. which statements are true based on the data? check all that apply. after adding the 0 test score, the mean would be the most appropriate measure of center to describe the data. after adding the 0 test score, the mean would be affected. after adding the 0 test score, the median would be the most appropriate measure of center to describe the data. before the missed test, eva’s median score was 96. before the missed test, eva’s median score was 91. before the missed test, eva’s mean score was 91.8.

we know that

1) Before the missed 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 adding the 0 test score

a) mean=[82+100+96+90+91+0]/5=459/6> 76.5

b) median

0,82,90,91,96,100> the median is [90+91]/2> 90.5

therefore

a) After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data> is true

b) After adding the 0 test score, the mean would be affected> is true

c) After adding the 0 test score, the median would be the most appropriate measure of center to describe the data> is false

d) Before the missed test, Eva’s median score was 96> is false

e) Before the missed test, Eva’s median score was 91 is true

f) Before the missed test, Eva’s mean score was 91.8> is true
