Given data:

standard deviation is 
As distribution is normal in shape and values are symmetrical
The standard deviation rule says that 95% of observation lies between the second standard deviation of the mean
so, approximately only 5% of observation lies outside the interval and normal shape is symmetric. hence approximately 0.15% of observation lies above the interval


almost 0.15% of students spent more amount is 529
The correct answer is C. 4π / 3
Hope this helps!
