G A random sample of 100 U. S. adults were selected from a population. In the population, the probability of having hypertension is about 24%. What is the probability that there are exact 30 people in the sample who have hypertension? (Round the result to 3 decimal places; I recommend you to use Minitab or other software. Use binomial distribution.)

0.03398 or 3.398%

Step-by-step explanation:

-This is a binomial probability problem.

-Given p=0.24, n=100, the probability that exactly 30 people is calculated as:

Hence, the probability that exactly 30 people have hypertension is 0.03398

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
