Question

ng tothe Textbook of Medical Physioloty, 5, Edition, by Arthur Guyton, 9% of the type of each. What is the probability that three of these people have blood type has type B blood. We will say we Anayze the following binomial experiment and determine p.g.n, an choose 18 people at random from the population and population has blood type B. Suppose we 8? (note: respect to the entire population.) in this experiment, we are observing whether or not a person have success if the person type B blood. What is failure? er mate Independence is aproximated because 18 people is an extremely small sample with a) b) The probability of success is 0.09, since 9% of the population has type B blood, what is the probability of failure.g? c) How many trials does this experiment have? d) In this case, we want to compute the probability of 3 successes out of 18 trials. What isr ? 3. Privacy is a concern for many use rs of the internet. One survey showed that 59% of Internet users are somewhat concerned about the confidentiality of their information, what is the probabilthy that for a random sample of 1 concerned about the privacy of their email? e-mail. Based on this

Explanation / Answer

Here sample size = 18

Here Pr(Population has blood type B) = 0.09

(a) Here failure is if person doesn't have type B blood.

(b) Probability of failure = 1 - 0.09 = 0.91

(c) There are n = 18 trials here.

(d) Here r = 3 as we have to find the probability of 3 successes.

Question3  

Here r= 6

n = 10

p = 0.59 ; q = 0.41

Pr(r = 6 ; 10) = 10C6 (0.59)6 (0.41)4 = 0.2503
