Answer: The percentile is 89

Step-by-step explanation:

This question can be solved using concept for t tables

In a normal distribution the curve. \mu= 1470 ,  \sigma = 230, x=1750

The relationship between z score, mean and standard deviation is given by

x = \mu+z\sigma

So the z value according to this is given by the formula

1750=1470+z(230)\\ z=\frac{280}{230} \\\\z = 1.217

From the z table we can infer that p value for z=+1.217 is 88.82

So 1750 is 89th percentile
