It is known that 40% of adult workers have a high school diploma. If a random sample of 10 adult workers is selected, what is th

Maurinko [17]

Answer:

The expected number of adult workers with a high school diploma is 4.

Step-by-step explanation:

This random variable X can be modeled with the binomial distribution, with parameters n=10 (the sample size) and p=0.4 (the probability that a adult worker have a high school diploma).

The expected value of X is then the mean of the binomial distribution with the parameters already mentioned.

This is calculated as:

$E(X)=\mu_b=n\cdot p=10\cdot0.4=4$
