Given : A game is designed such that it would take 35 attempts to reach level 125. The variance of the players who have reached the level is found to be 25. A has reached level 124 after 38 attempts and it took him two
more to reach the next.
To Find : What is his z statistic
Solution:
Mean = 35
Variance = 25
SD = √variance = √25 = 5
reached level 124 after 38 attempts and it took him two
more to reach the next.
Hence 38 + 2 = 40 attempts to reach level 125
Z score = ( value - mean )/ SD
= ( 40 - 35)/5
= 5/5
= 1
Hence his z score is 1
