Faisal has a height of 103.1 centimeters.

Since the heights are normally distributed,

So Faisal's height is 103.1 - 105 = -1.9 cm relative to the mean.

This is \frac{-1.9}{10}=-0.19\ cm standard deviations relative to the mean.

This is Faisal's z-score.

We want to find the proportion of heights below the z-score of -0.19.

This is 0.42465

Rounding this off to 4 decimal places gives us 0.4247

So **0.4247 **proportion of student heights are lower than Faisal's height.
