Question

a batsman scored the following number of runs in 6 innings 36,35 ,50 ,46 ,60, 55. calculate the mean runs scored by him in an innings

Answer 1

the formula for mean is= sum of all observations/total number of observation
 so we get     (36+50+55+46+60+35)/6
                                     = 282/6
                                     =47 is the  mean 

Answer 2

mean = sum of observations/total observations
mean = (36 + 35 +50 +46 + 60 + 65)/6
mean = 282/6
mean = 47.
mean score = 47 runs per innings
