According to the 68-95-997 rule, 68 percent of IQ within +/- 1 standard deviation of the mean for a normal distribution. This corresponds approximately to what Intelligence Classification? Another school wants to serve the needs of the \"middle\" 99.7 percent of adults. Use the 68-95-997 rule and determine which 115-129 Intelligence Classifications will be EXCLUDED from classes at this 130-144 school. t we are looking at?

name distribution: distribution by intervals
parameters: IQ range
variable: quantitative
b)
mean +/- standard deviation: 68%
100+15 =115
100-15 = 85
the 68% of this distribution corresponds to IQ between 85 and 115
c)
mean - 3 sigma
mean + 3 sigma
100- 3*15 =55
100 + 3*15 =145
99.7% will be between 55 and 145
IQ excluded will be 1-54 and greater than 146
