Would you say this is an unusual height? Why or why not? 5. In 1986, the US Federal Reserve sampled abow 1000

Answer 1

a]	For a normal distribution, 95% of items fall within
	mean +/- 2 standard deviations.
	Hence, the interval is 65+2*3.5 and 65-2*3.5 =
	between 72 inches and 58 inches.
b]	The height of the woman is 65+3*3.5 = 75.5 inches.
	It is an unusual height as 99.7% of the persons would
	fall between Mean +/- 3 standard deviations. This would
	mean that only 0.3%/2 = 0.15% would be above 75.5 inches
