For any measured sample proportion x, the z score is given by:
The population proportion is 0.53
At the 14th percentile, the corresponding z-score is z =-1.08.
Since 0.48 is at the 14th percentile, the standard deviation is:
Therefore, the sample size 'n' is given by:
The sample size must have been of 116 students.
