2. In California, Senate Bill 1368 limits the amount of CO2 that power plants can emit. The standard is 1100 lbs of CO2 per Megawatt (MW) of electrical power that is generated (on average). You suspect that the power plant exceeds the standard. (Data attached below.) What is the null hypothesis? What is the alternative hypothesis? Explain real-world consequences of making a Type 1 error. Explain real-world consequences of making a Type 2 error. Is a hypothesis test for this case left-tailed, right-tailed, or two-tailed? Do the data supply evidence of the power plant exceeding the pollution standard?
