You know from government data that heights of young men are approximately Normal with standard deviation about 2.8 inches. You want your sample mean x⎯⎯⎯ to estimate μ with an error of no more than one-half inch in either direction. (a) What standard deviation must x⎯⎯⎯ have so that 68% of all samples give an x⎯⎯⎯ within one-half inch of μ

Consider circle o, where and . m∠bpd °. °.
