**Transcription of the Educational Content on Climate Change Beliefs and Political Ideology** **Overview** A 2010 Pew Research poll asked 1,306 Americans, "From what you’ve read and heard, is there solid evidence that the earth is warming?” The distribution of responses by party and ideology has been presented below. Frequency counts have been replaced with relative frequencies. **Table: Distribution of Belief in Global Warming by Political Ideology** | | Conservative Republican | Mod/Cons Democrat | Liberal Democrat | Total | |-----------------------|-------------------------|--------------------|------------------|-------| | **Earth is warming** | 0.06 | 0.18 | 0.10 | 0.34 | | **Not warming** | 0.10 | 0.07 | 0.02 | 0.19 | | **Don’t know/refuse** | 0.04 | 0.08 | 0.02 | 0.14 | | **Total** | 0.20 | 0.33 | 0.14 | 0.67 | **Questions and Exercises** *a) Are believing that the earth is warming and being a liberal Democrat mutually exclusive?* - Yes - No *b) What is the probability that a randomly chosen respondent believes the earth’s warming?* *Answer:* (place your calculation here) *c) What is the probability that a randomly chosen respondent believes the earth is warming given that he is a liberal Democrat?* *Answer:* (place your calculation here) *d) What is the probability that a randomly chosen respondent believes the earth is warming given that he is a conservative Republican?* *Answer:* (place your calculation here) *e) Interpret your calculated probabilities in parts c and d.

Expert Solution
Step 1

I have solved first three parts. (a), (b), (c)

Let event A : be the Earth is warming

     event B :  be the Liberal Democrat

P(A)=0.6

P(B)=0.2

P(A and B)=0.18      

Step 2

a) The earth is warming and being a liberal Democrat are not mutually exclusive.

Since P(A and B)= 0.18 ≠0
