Fourteen of the major pundits/outlets provided race ratings for Colorado, and a supermajority of them (nine to be exact) said that Colorado was NOT a safe bet for Biden. In this Problem, you will use hypothesis testing to evaluate the effectiveness of pundits' predictions for the 2020 Presidential Election in Colorado. By 3 November 2020, the polling average for the State of Colorado was Biden ahead of Trump by 12.4%. For the purposes of this Problem, we will aggregate the polls into an average sample size of n 1000. In this case, that would result in a-562 and 30. Assume that being above 500 results in a Biden win with all other outcomes resulting in a Trump win. Suppose that 99.99% confidence or higher is high enough to definitively state that Colorado is a safe bet for Biden (e. "Safe Biden"). Hence, what would our two hypotheses be? OAHO:#05 HA:M>0.5 OBHO: 500 HA:M> 500 O0.HO:>05 HA: 0.5 OD. Ho: /> 500 HA: 500 QUESTION 2 Refer to the scenario from Question #1. Now, you will perform the hypothesis test by using the p-value approach. First, identify the value of alpha from the options below. OA 0.001 OB.0.1 OC.0.01 D. 0.0001 JESTION 3 Refer to the scenario from Question #1. Next, you will use either the normal distribution or the r-distribution. Which distribution should be used and why? A. We will use the 1-distribution because the population mean is unknown. B. We will use the normal distribution because the population mean is unknown. C. We will use the t-distribution because the population standard deviation is unknown.
