Answer:
I have given it step by step below.
Step-by-step explanation:
(i) Mean = sum of observations/total no. of observation
= 23 + 20 + 4 + 19 + 28 + 35 + 25 + 0 +1 + 30/ 10
= 185/10
= 18.5
(ii) additional 35 runs
New Mean
=previous total + 35/10 + 1 (the 1 gets added in denominator because of the additional observation)
= 185 + 35/11
= 220/11
= 20
