Calculate the % of a 9-inning MLB games resulting in 5 or fewer hits.
An analysis was done to study the odds of # of hits in MLB for all 9 inning MLB Games played b/w 1960-2005. The distribution of hits/9-inning is approximately normal w/mean of 7.52 & std of 1.10.
The words “approximately normal” are a clue that we need to use z-scores. The z-score formula is
z = (x – mean) / st. dev.
In this problem, we have the following values:
x = 5
mean = 7.52
st. dev. = 1.10
If we plug …
This solution shows how to calculate the % of MLB games that result in 5 or fewer hits, using statistics.
