=> 
The probability that the sample mean height is greater than 66 inches

=> 
=> 
From the z-table the value of 
=> 
Considering b
sample mean is n = 100
Generally the standard error of mean is mathematically represented as

=> 
The probability that the sample mean height is greater than 66 inches

=> 
From the z-table the value of
