Exercise 26 proposes modeling iq scores with n(100, 16). what iq would you consider to be unusually high? explain.

1 answer:

5 0

<span>N(100, 16) means a normally distributed population with a mean of 100 and a standard deviation of 16.

Using the 95% confidence level factor (1-tail), which is approximately 1.65, then, any IQ that exceeds:

100 + 16*1.65 is higher than 95% of the population. I'd consider that unusually high.</span>
