Suppose that Body Mass Index (BMI) for a population of 30-60-year-old men follows a Normal distribution with mean 26, and standard deviation 4.
From a random sample of 7 men aged 30-60 years old, what is the probability that the average BMI of these 7 men is equal to or larger than 30?
What is the probability that more than 4 of these 7 are obese (i.e. BMI ≥ 30)?
