#### Answer

approximate 68% of the population fall in [66,98] when k=1
approximate 95% of the population fall in [50,114] when k = 2
approximate 99.7% of the population fall in [34,130] when k = 3

#### Work Step by Step

Interval:
x`+-1s = 82+- 1(16) = [66,98]
x`+-2s = 82+- 2(16) = [50,114]
x`+-3s = 82+- 3(16) = [34,130]
