Answer:
a) 21
b) 21
Step-by-step explanation:
Given 10 scores: 19, 15, 34, 29, 13, 35, 10, 19, 14, 22
a) Mean
= (sum of scores) / number of scores
= (19+15+ 34+ 29+ 13+ 35+ 10+ 19+ 14+ 22) / 10
= 210 / 10
= 21
b) one more score of 21 is added
hence
number of scores = 10 + 1 = 11
sum of scores = 210 + 21 = 231
Mean = (sum of scores) / number of scores
= 231 / 11
= 21
