Testing a Hypothesis about a Population proportion:

1. Suppose that you conduct a study on your situation in which the sample statistic produces a test statistic of 2.13. a. Based upon your level of significance from 3 part 4, would you reject or fail to reject the null hypothesis? Explain your decision. b. Determine a level of significance that would have the opposite result of 4 a part i. Explain why this level of significance would have the opposite result

***the level of significance from 3 part 4 is 0.05***

My poll question is as following:

Quinnipiac University Poll. Jan. 28-Feb. 1, 2021. N=1,075 adults nationwide. Margin of error 3. "Do you support or oppose the Biden administration re-joining the Paris Agreement, a pact reached among countries around the globe to limit climate change by reducing greenhouse gas emissions?" 1/28 - 2/1/21 Support 63% Oppose 33% Unsureo answer 4%

***I attached a confidence interval template for known and unknown successes incase you need it.***

Confidence Interval for Proportion [Number of Success Unknown} Sample Size Confidence Level Proportion of sample 63.90% 2 - score for the left side of the confidence interval -1.95996 2 - score for the right side of the confidence interval 1.95996 Standard Error of the proportion 0.91413 Lower Limit = proportion - standard error*z -score 9.69114 Upper Limit = proportion + standard error*z -score right side 0.65666
