[Q4: Only answer if you ABSOLUTELY know how to solve AND the answers match up ((tired of getting wrong replies.) So, please make sure you’re really certain. [It’s appreciated.])
Really Explain EACH STEP, including any formulas you used (& how to use the formula), and explain how to compute with a TI-84 preferably/when possible.]
NO JUST POSTING THE ANSWER WITH NO EXPLANATION/ NO CONVINCING EXPLANATION, I WILL ASSUME IT'S WRONG, AS HAS BEEN THE CASE BEFORE. IF YOU'RE THIS TYPE, MOVE ON.
A USA Today article claims that the proportion of people who believe global warming is a serious issue is 0.71, but given the number of people you've talked to about this same issue, you believe it is greater than 0.71. The hypotheses for this test are Null Hypothesis: p 0.71, Alternative Hypothesis: p > 0.71. You take a random sample and perform a hypothesis test, getting a p-value of 0.6579. What is the appropriate conclusion? Conclude at the 5% level of significance.
Question 4 options:
1)
The proportion of people who believe global warming is a serious issue is significantly larger than 0.71.
2)
The proportion of people who believe global warming is a serious issue is less than or equal to 0.71.
3)
We did not find enough evidence to say a significant difference exists between the proportion of people who believe global warming is a serious issue and 0.71
4)
We did not find enough evidence to say the proportion of people who believe global warming is a serious issue is less than 0.71.
5)
We did not find enough evidence to say the proportion of people who believe global warming is a serious issue is larger than 0.71.

5)
We did not find enough evidence to say the proportion of people who believe global warming is a serious issue is larger than 0.71.
Explanation / Answer
Given P-value of 0.6579 which is > alpha 0.05, so we accept H0
Correct Answer : Option (2) The proportion of people who believe global warming is a serious issue is less than or equal to 0.71.
i.e. Null Hypothesis: p 0.71
