The following are the last 10 run scores colin got in cricket:
19, 15, 34, 29, 13, 35, 10, 19, 14, 22
a) work out colin's mean score.
b) colin plays cricket again on sunday. he gets 21 runs.
what is his new mean score?

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
