Scores on the GRE (Graduate Record Examination) are normally distributed with a mean of 594 and a standard deviation of 96. Use the 68-95-99.7 Rule to find the

percentage of people taking the test who score below 306.

The percentage of people taking the test who score below 306 is

%.

0.15%

Step-by-step explanation:

The Empirical Rule ( 68-95-99.7 Rule) states that almost all data falls within 3 standard deviations of the mean for a normal distribution.  Under the rule:

Given that:

mean (μ) = 594 and standard deviation σ = 96

The percentage of people that all fall outside 306 and 882 = 100% - 99.7% = 0.3%. Therefore the percentage of people that are below 306 = 0.3% / 2 = 0.15%

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
