Answer:
The mean is the better method.
Step-by-step explanation:
The best way to meassure the average height is throught mean. The mean of a sample is the average of that sample's height, and it will be a good estimate for the population's average height.
The mode just finds the most frequent height. Even tough the most frequent height will influence the average height, knowing only what height is the most frequent one doesnt give you enough informtation about how the height is centrally distributed.
As for the median, it is fine to use the median of a sample to estimate the median of the population, but if you use the median to estimate the average height you may have a few issues. For example, if you include babies in your population, the babies will push the average height down a lot and they are far below te median height. This, as a result, will give you a median height of a sample way above the average height of the population, becuase median just weights every person's height the same, while average will weight extreme values more, in the sense that a small proportion of extreme values can push the average far from the median.

Step-by-step explanation:
From the question we are told that
The daily demand is 
The standard deviation is 
The service probability is 
The number of chips in the inventory is 
The number of days in his monthly is 
The lead time is 
Generally the number he should order (optimal order ) is mathematically represented as
Here 
is the monthly standard deviation which is mathematically evaluated as
=> 
=> 
Also z-value for the 95% service probability from the z-table is 1.96
So
=>
For the maximum order quantity k = 0
So
=> 
=>
