In the united states, the mean age of men when they marry for the first time follows the normal distribution with a mean of 29 years. the standard deviation of the distribution is 2.5 years. for a random sample of 60 men, what is the likelihood that the age when they were first married is less than 29.3. years?

Step-by-step explanation:

Let X represent the age of men when they marry for the first time  in the United States.

Given x bar follows normal with mean = 29 years and sigma = 2.5 years

Sample size =n= 60 men

Std error of sample =

The  likelihood that the age when they were first married is less than 29.3. years

=0.8238
