In a recent poll about a Green New Deal, 1025 respondents were asked the following question: Would you support or oppose a Green New Deal, a policy in which the Federal government creates jobs and invests in low-income communities building energy efficient infrastructure, replacing lead water pipes, and updating America's energy grid? About 55% of respondents said that they supported the Green New Deal and the rest either opposed the deal or were unsure. For this problem assume that the respondents form a representative sample of the US population. Then does this poll provide convincing evidence that a majority of Americans support a Green New Deal? (a) State the appropriate null and alternative hypotheses. HO: P=0.5 Ha: P>0.5 It is a one-sided z test for proportion (b) Calculate the test statistic and determine the p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.) z- 3.22 p-yalue -.0006

In a recent poll about a Green New Deal, 1025 respondents were asked the following question:
Would you support or oppose a Green New Deal, a policy in which the Federal government creates jobs and invests in low-income communities building energy efficient infrastructure, replacing lead water pipes, and updating America's
energy grid?
About 55% of respondents said that they supported the Green New Deal and the rest either opposed the deal or were unsure. For this problem assume that the respondents form a representative sample of the US population. Then does
this poll provide convincing evidence that a majority of Americans support a Green New Deal?
(a) State the appropriate null and alternative hypotheses.
Но: P-0.5
Ha: P>0.5
It is a one-sided z test for proportion
(b) Calculate the test statistic and determine the p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.)
Z = 3.22
