Answer:

a) 99.7%

b) 68%

Explanation:

[tex]\mu[/tex] = Mean = 168 cm

[tex]\sigma[/tex] = Standard deviation = 6 cm

a. 150 cm and 186 cm

[tex]168-6\times 3=150[/tex]

[tex]168+6\times 3=186[/tex]

They vary by 3 standard deviations. So, 99.7% of men are between 150 and 186 cm

b. 162 cm and 174 cm

[tex]168-6\times 1=162[/tex]

[tex]168+6\times 1=174[/tex]

They vary by 1 standard deviations. So, 68% of men are between 162 and 174 cm
