The distribution of the amount of money spent by students on textbooks in a semester is approximately normal in shape with a mea
Archy [21]

Answer:

Step-by-step explanation:

Given data:

\mu = 473

standard deviation is \sigma=  28

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

             = \mu + 2\times \sigma

             = 473 + 2\times 28 = 529

almost 0.15% of students spent more amount is 529
