Chapter 3: Q.74 (page 221)

Use the following information to answer the next 12 exercises. The graph shown is based on more than interviews done by Gallup that took place from January through December 2012. The sample consists of employed Americans 18years of age or older. The Emotional Health Index Scores are the sample space. We randomly sample one Emotional Health Index Score.

What is the probability that an Emotional Health Index Score is less than 80.2given that it is already less than 81.

Short Answer

Expert verified

The probability that an Emotional Health Index Score is0.4286

Step by step solution

01

Introduction

The scientific skill of likely hood are often wont to analyze variance. It it's interested with the prospect (probability) of just a happening occurring. If you spin a a good coin multiple times, the results statistically probable to be two heads and two tails.



02

Probability score

There must be seven contests with only a result compared with fewer least 81.credits. And there are three contests with only a value little less that 80.2amid it. Thus suggests that its possibility is computed as follows:

P=37=0.4286

Forty-eight percent of all Californians registered voters prefer life in prison without parole over the death penalty for a person convicted of first degree murder. Among Latino California registered voters, 55%prefer life in prison without parole over the death penalty for a person convicted of first degree murder. 37.6%of all Californians are Latino. In this problem, let: • C = Californians (registered voters) preferring life in prison without parole over the death penalty for a person convicted of first degree murder. L = Latino Californians. Suppose that one Californian is randomly selected.

Are L and C mutually exclusive events? Show why or why not

Use the following information to answer the next two exercises. You are rolling a fair, six-sided number cube. Let E = the event that it lands on an even number. Let M = the event that it lands on a multiple of three.

What does P(E|M) mean in words?

Let B = the event of getting a blue jelly bean

Let G = the event of getting a green jelly bean.

Let O = the event of getting an orange jelly bean.

Let P = the event of getting a purple jelly bean.

Let R = the event of getting a red jelly bean.

Let Y = the event of getting a yellow jelly bean.

Find P(O).
