The mean test score in Miss Smith’s 4th grade class was 73, with a standard deviation of 4. Assume the grades are normally distributed and use the Empirical Rule (68-95-99.7) to find the approximate percentage of students who scored above 81.

Choose a second initial value that is 0.01 greater than the initial value from question 9. iterate it using the function, f, ten times. if necessary, you can round your results to the nearest ten-thousandth.
