1 < Question 18 of 24 >Slow response times by paramedics, firefighters, and policemen can have serious consequences for accident victims. In the caseof life-threatening injuries, victims generally need medical attention within 8 minutes of the accident, Several cities have begunto monitor emergency response times. In one such city, emergency personnel took more than 8 minutes to arrive on 22% of allcalls involving life-threatening injuries last year. The city manager shares this information and encourages these first respondersto "do better." After 6 months, the city manager selects an SRS of 400 calls involving life-threatening injuries and examines theresponse times. She then performs a test at the a a = 0.05 level ofHọ p = 0.22Hp< 0.22where p is the true proportion of calls involving life-threatening injuries during this 6-month period for which emergencypersonnel took more than 8 minutes to arrive.Which type of error is more serious in this case? Justify your answer.OA Type II error would be more serious because the city would underestimate the ability of the emergency personnel toget to the scene quickly and would keep trying to get the response times lower.O A Type I error would be more serious because the city would overestimate the ability of the emergeney personnel to getto the scene quickly and people may end up dying.O A Type I error would be more serious because this would mean that more people are suffering life-threatening injuries.A Type I error would be more serious because this would mean that some life-threatening injuries aren't treated at allwhen they should be.O A Type Il error would be unore serious because the city would underestimate the ability of the emergeney personnel toget to the scene quickly and more people will get treatment than expected.

Type I and Type III errors are critical to hypothesis testing in statistics.

Slow response times by paramedics, firefighters, and policemen can have serious consequences for accident victims. In the case of life-threatening injuries, victims generally need medical attention within 8 minutes of the accident. Several cities have begun to monitor emergency response times. In one such city, emergency personnel took more than 8 minutes to arrive on 22% of all calls involving life-threatening injuries last year. The city manager shares this information and encourages these first responders to "do better." After 6 months, the city manager selects an SRS of 400 calls involving life-threatening injuries and examines the response times. She then performs a test at the a a - 0.05 level of Ho p- 0.22 H, p< 0.22 where p is the true proportion of calls involving life-threatening injuries during this 6-month period for which emergency personnel took more than 8 minutes to arrive.
