Question
In the NFL, Coaches can throw "challenge" flags if they believe officials have made an incorrect call on the field. Then, based upon further
analysis, the call is either overturned (because the referees were incorrect) or upheld (referees were correct). In the first eight weeks of last
NFL season, there were 316 challenges made, with 154 of those calls overturned.
The NFL team owners used this data to begin a lawsuit that claimed referees were wrong more than 50% of the time in challenged
situations. They want to perform statistical analysis before filing that lawsuit.
For the following question, select the answer which correctly responds.
If a significance level of 0.05 was chosen for this analysis, what confidence level should be used to test this claim using the Confidence Interval
Method?
O 95%
O 90%
10%
O 5%
