Use this order in calculating the difference so that the difference is positive. Answer the following questions.Construct a Confidence Interval of the difference in proportions. Do not assume equal variances for this calculation. Show all the parts: the estimated difference; the critical z-value, the standard error, the BOE, and the lower and upper values. Is zero within your confidence interval? Conduct a Hypothesis Test that the difference of the two proportions is zero. Use an alpha level of .01. This will be a 2-tailed test. Note that this requires a pooled estimated of the standard error.

<u><em>The increased heat, disruption to the water cycle and loss of shade would take a deadly toll on billions of people and livestock. Poverty and death would also descend on many of the 1.6 billion people who currently rely directly on forests for their livelihoods, including for harvesting food and medicine. </em></u>

<u><em>When Amazon rainforest disappears, so does Amazon rain. That's because air passing over forests picks up moisture given off by trees and plants, fueling rains. ... When those trees disappear, so does some of that rain.</em></u>

<u><em>The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.</em></u>

<u><em>In conclusion...Without trees, we all die. Besides providing oxygen for us to breathe, trees make life on earth sustainable. ... Trees affect everything from the air we breathe to the rain that falls from the sky. Without a robust population of trees, we die and so does our planet.</em></u>
