find the age of men such that 80% of them were married for the first time by that age, P80, P(x <d) = 0.8000 34.6 30.6 32.6 25.6
The age at which men in United States marry for the first time follows the normal distribution with a mean μ = 26.8 year

The age at which men in United States marry for the first time follows the normal distribution with a mean μ = 26.8 years with the standard deviation of the distribution o = 4.5 years. If one married man is selected at random, find the probability that the age at which he married for the first time was less than 25, P(x < 25)
