Chapter 5: Q. 5.66. (page 211)

A survey was conducted in canada to ascertain public opinion about a major national park region in the Banff -Bow valley. One question asked the amount that respondents would be willing to contribute per year to protect the environment in the Banff - Bow Valley region. the following frequency distribution was found in an article by J Ritchie et al titled "Public reaction to policy Recommendation from the Banff - Bow valley study" (journal of sustainable tourism, vol, 10 No. 4.pp 295 - 308).

For a respondent selected at random. Let

A = event that the respondent would be willing to contribute at least \(101.

B = event that the respondent would not be willing to contribute more than \)50.

C = event that the respondent would be willing to contribute between \(1 and \)200.

D = event that the respondent would be willing to contribute at least $51.

Describe the following events in words and determine the number of outcomes (respondents) that make up each event.

Part (a) (not D)

Part (b) (A & B)

Part (c) (C & A)

Part (d) (B &D)

Short Answer

Expert verified

Part (a) Number of outcome=85

Part (b) Number of outcome=0

Part (c) Number of outcome =219

Part (c) Number of outcome=116

Step by step solution

01

Part (a) Step 1. Given information.

The following frequency distribution was discovered in the publication "Public Reactions to Policy Recommendations from the Banff-Bow Valley Study" by J. Ritchie et al.

Contribution (S)Frequency
085
1 - 50116
51 - 10059
101 - 20029
201 - 3005
301 - 5007
501 - 10003

For a respondent selected at random. Let

A = event that the respondent would be willing to contribute at least $101.

B = event that the respondent would not be willing to contribute more than $50.

C = event that the respondent would be willing to contribute between $1 and $200.

D = event that the respondent would be willing to contribute at least $51.

02

Part (a) Step 2. (not D) the event in words, as well as the number of outcomes that make it up.

(not D) is the situation in which the respondent is unwilling to provide anything.

Number of outcome=85

03

Part (b) Step 1. Given information.

The following frequency distribution was discovered in the publication "Public Reactions to Policy Recommendations from the Banff-Bow Valley Study" by J. Ritchie et al.

Contribution (S)Frequency
085
1 - 50116
51 - 10059
101 - 20029
201 - 3005
301 - 5007
501 - 10003

For a respondent selected at random. Let

A = event that the respondent would be willing to contribute at least $101.

B = event that the respondent would not be willing to contribute more than $50.

C = event that the respondent would be willing to contribute between $1 and $200.

D = event that the respondent would be willing to contribute at least $51.

04

Part (b) Step 2. The event (A & B) and the number of outcomes that make up the event.

The null event is (A & B). There are no outcomes in common between Events A and B.

Number of outcome

(A&B)=0

05

Part (c) Step 1. Given information.

The following frequency distribution was discovered in the publication "Public Reactions to Policy Recommendations from the Banff-Bow Valley Study" by J. Ritchie et al.

Contribution (S)Frequency
085
1 - 50116
51 - 10059
101 - 20029
201 - 3005
301 - 5007
501 - 10003

For a respondent selected at random. Let

A = event that the respondent would be willing to contribute at least $101.

B = event that the respondent would not be willing to contribute more than $50.

C = event that the respondent would be willing to contribute between $1 and $200.

D = event that the respondent would be willing to contribute at least $51.

06

Part (c) Step 2. The event (C & A) and the number of outcomes that make up the event.

(C or A) is the scenario in which the respondent is willing to contribute at least $1.

Number of outcome

(CorA)=116+59+29+5+7+3(CorA)=219

07

Part (d) Step 1. Given information.

The following frequency distribution was discovered in the publication "Public Reactions to Policy Recommendations from the Banff-Bow Valley Study" by J. Ritchie et al.

Contribution (S)Frequency
085
1 - 50116
51 - 10059
101 - 20029
201 - 3005
301 - 5007
501 - 10003

For a respondent selected at random. Let

A = event that the respondent would be willing to contribute at least $101.

B = event that the respondent would not be willing to contribute more than $50.

C = event that the respondent would be willing to contribute between $1 and $200.

D = event that the respondent would be willing to contribute at least $51.

08

Part (d) Step 2. The event (B & D) and the number of outcomes that make up the event.

(B & D) is the scenario in which the respondent is ready to contribute somewhere between $1 and $50.

Number of outcome

(B&D)=116

Answer true or false to each statement and explain your answers.

(a) For any two events, the probability that one or the other of the events occurs equals the sum of the two individual probabilities.

(b) For any event, the probability that it occurs equals 1 minus the probability that it does not occur.

Answer true or false to the following statement and justify your answer. If event A and event B are mutually exclusive, neither are events A,B and C for every event C.

Discuss the pros and cons of binomial probability tables.

In Exercises 5.16-5.26, express your probability answers as a decimal rounded to three places.

Preeclampsia. Preeclampsia is a medical condition characterized by high blood pressure and protein in the urine of a pregnant woman. It is a serious condition that can be life-threatening to the mother and child. In the article "Women's Experiences Preeclampsia: Australian Action on Preeclampsia Survey of Wom and Their Confidants" (Journal of Pregnancy,Vol. 2011, Issue 1, Article ID 375653), C. East et al. examined the experiences of 68 women with preeclampsia. The following table provides a frequency distribution of instances of prenatal or infant death for infants of women with preeclampsia.

Suppose that one of these women with preeclampsia is randomly selected. Find the probability that the child of the woman selected

(a) died.

(b). died one week to six months after birth.

(c). lived at least six weeks.

For each of the following probability histograms of binomial distributions, specify whether the success probability is less than, equal to, or greater than 0.5. Explain your answers.
