Question
II. D and E Handwritten
Solve the problem and draw the normal curve with the shaded region
representing the given scenario in the problem. Explicitly write your
solution and state & highlight your final answer at the end.
You have just received your score in a mathematics aptitude
test. Given your score was 82
and the mean score on the test was 73 with a standard deviation
of 5. Assume that the test scores are normally distributed.
a. Find the median and the mode, and compare it with the given
mean value.
b. Determine the intervals within 1, 2 and 3 standard deviations
from the mean, that is, the u ± 10, p ± 20, p± 30.
c. Verify that the empirical rule holds that is, approximately, 68%,
95%, and 99% of the data lie within ± 10, ± 20, ± 30 units of
the mean, respectively.
d. How does your score compare with the distribution of all test
scores?
c. What is the probability that for the scores that would fall
between 40 and 45?
