Suppose that IQ scores have a bell-shaped distribution with a mean of 101 and a standard deviation of 12. Using the empirical rule, what percentage of IQ scores are between 77 and 125?

Answers

Answer 1

95.44% IQ scores are between 77 and 125

We're given,

Mean (a)=101

standard deviation (b)=12

To find : [tex]P[77 < x < 125][/tex]

Using Empirical Rule:

∴ [tex]P[77 < x < 125][/tex]  [tex]=[/tex] [tex]P[\frac{77-101}{12} < \frac{x-a}{b} < \frac{125-101}{12}]\\[/tex]

[tex]=P[-2 < z < 2]\\[/tex]

[tex]=P[Z < 2]-P[Z < -2]\\[/tex]

[tex]=0.9772-0.0228\\[/tex]

[tex]=0.9544[/tex] =95.44% (approx)
