The mean age for young adults to get married is normally distributed with a a mean of 29.8 years and a standard deviation 6.7 years old. What is the probability that a random sample of 45 U. S adults mean age when they were married at most 32 years old? (round to 4 decimal places)
My approach was following: 6.7/√ 45 =0.9987770299. TI-84 calculator, normal CDF: (-1E99, 32, 29.8, 0.9987770299)
Result: 0.9862
Can anyone confirm if this is correct please?
