Suppose that heights of adult men follow a normal distribution with mean μ=171.5cm
and standard deviation σ=6.5cm. Find the following probabilities using normal tables
(i) Probability that a randomly selected man is taller than 180 cm
(ii) Probability that a randomly selected man is shorter than 160 cm
(iii) Probability that a randomly selected man is between 165 cm and 175 cm
