The following figure shows the normal distribution with the proportion of the area under the normal curve contained within one, two, and three standard deviations of the mean. The last proportion on each side, 0.13%, depicts the remaining area under the curve. Specifically, 0.13% of the area under the standard normal distribution is located above z-score values greater than the mean (u) plus three standard deviations (+30), Also, because the normal distribution is symmetrical, 0.13% of the area under the standard normal distribution is located below 2-score values less than the mean (w) minus three standard deviations (-30). 34.13% 34.13% 13,59% 13.59% 2.15% 2.15% 0.13% -30 0.13% +30 -20 +1a +20 Use the figure to help you answer the following questions.

The main NAEP assessments are conducted annually on samples of students from grades 4, 8, and 12. In 2000, the science scores for female students had a mean of 146 with a standard deviation of 35. Assume that these scores are normally distributed with the given mean and standard deviation. A score of 111 is v below the mean, while a score of 181 is v above the mean. This means that the percentage female students with scores between 111 and 181 is A score of 216 is v above the mean.

The following figure shows the normal distribution with the proportion of the area under the normal curve contained within one, two, and three
standard deviations of the mean. The last proportion on each side, 0.13%, depicts the remaining area under the curve. Specifically, O.13% of the area
under the standard normal distribution is located above z-score values greater than the mean (P) plus three standard deviations (+3o). Also, because
the normal distribution is symmetrical, 0.13% of the area under the standard normal distribution is located below z-score values less than the mean
(H) minus three standard deviations (-30).
