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?

Question
Transcribed Image Text: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 sale
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 2562 and a 30. Assume that ja 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?.

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

QUESTION 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?
OA. We will use the t-distribution because the population mean is unknown.
B. We will use the normal distribution because the population mean is unknown.
OC. We will use the t-distribution because the population standard deviation is unknown.
