Chapter 6: Q. 78 (page 404)

78. Rhubarb Refer to Exercise 76. Would you be surprised if 3 or more of the plants in the bundle die before producing any rhubarb? Calculate an appropriate probability to support your answer.

Short Answer

Expert verified

The probability is less than 5%,ThereforeP(X鈮�3)=1.16%and the result is surprising.

Step by step solution

01

Given information

Three or more of the plants in the bundle die before producing any rhubarb.

02

Explanation

Given, n=10and p=0.05

The Binomial Probability:

P(X=k)=nk脳pk脳(1鈭�p)n鈭�k

P(X=0)=100脳(0.05)0脳(0.95)10鈭�0鈮�0.5987

P(X=1)=101脳(0.05)1脳(0.95)10鈭�1鈮�0.315

P(X=2)=102脳(0.05)2脳(0.95)10鈭�2鈮�0.0746

P(X鈮�3)=1鈭�P(X=0)鈭�P(X=1)鈭�P(X=2)=1鈭�0.5987鈭�0.3151鈭�0.0746=0.0116=1.16%

Binomial setting? A binomial distribution will be approximately correct as a model for one of these two settings and not for the other. Explain why by briefly discussing both settings. (a) When an opinion poll calls residential telephone numbers at random, only 20%of the calls reach a person. You watch the random digit dialing machine make 15calls. Xis the number that reaches a person

(b) When an opinion poll calls residential telephone numbers at random, only 20%of the calls reach a live person. You watch the random digit dialing machine make calls. Yis the number of calls until the first live person answers

Fire insurance Suppose a homeowner spends \(300for a home insurance policy that will pay out \)200,000if the home is destroyed by fire. Let Y=the profit made by the company on a single policy. From previous data, the probability that a home in this area will be destroyed by fire is 0.0002.

(a) Make a table that shows the probability distribution of Y.

(b) Compute the expected value of Y. Explain what this result means for the insurance company
