Assume that 500,000 people take the ged exam (high school proficiency exam) each year and their scores form a normal distribution. what percent of students score within one standard deviation of the mean?

68.27%

Step-by-step explanation:

Assuming a normal distribution, the empirical 68–95–99.7 rule, determines that the percentage of students that score within one standard deviation of the mean is 68.27%, the percentage within two standard deviations is 95.45% and within 3 standard deviations is 99.73%.

Therefore, the answer is 68.27%.

step-by-step explanation: yes

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
