In late March 2020, a research firm conducted a national poll of 1055 U.S. adults that asked their views on the federal COVID-19 economic stimulus package. The question was, “As you may know, Congress is considering a new economic stimulus package of at least 2 trillion dollars. Do you favor or oppose Congress passing this legislation?” Of those sampled, 534 favored passage. At the 5% significance level, do the data provide sufficient evidence to conclude that the percentage of U.S. adults that favor the passage is greater than 50%?

Procedure: Select an answer One mean T Hypothesis Test One mean Z Hypothesis Test One variance χ² Hypothesis Test One proportion Z Hypothesis Test

Assumptions: (select everything that applies)

Step 1. Hypotheses Set-Up:

$\displaystyle {H}_{{0}}:$  Select an answer μ σ² p =	, where Select an answer p μ σ² is the Select an answer population mean population proportion population variance and the units are Select an answer subjects 100%
$\displaystyle {H}_{{a}}:$ Select an answer p μ σ² ? < ≠ >	, and the test is Select an answer Left-Tail Two-Tail Right-Tail

Step 2. The significance level $\displaystyle \alpha=$ %

Step 3. Compute the value of the test statistic: Select an answer z₀ χ²₀ f₀ t₀ = (Round the answer to 3 decimal places)

Step 4. Testing Procedure: (Round the answers to 3 decimal places)

CVA	PVA
Provide the critical value(s) for the Rejection Region:	Compute the P-value of the test statistic:
left CV is and right CV is	P-value is

Step 5. Decision:

CVA	PVA
Is the test statistic in the rejection region?	Is the P-value less than the significance level?
? no yes	? no yes

Conclusion: Select an answer Do not reject the null hypothesis in favor of the alternative. Reject the null hypothesis in favor of the alternative.

Step 6. Interpretation:

At 5% significance level we Select an answer DO DO NOT have sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis.
