Question

The LifeSaver emergency helicopter service is available for medicalemergencies occurring between 15 and 90 miles from its basehospital. Emergencies that occur closer than 15 miles are moreefficiently handled by the local ambulance service. A long termstudy of this service shows that the response time - T - (fromdispatch to arrival on the scene) is a normally distributedvariable with an average () of 38.00 minutes and astandard deviation () of 15.00 min. For each of theproblems below, find the appropriate probability.
Note: For problems A, B, and Cround your answers to four decimal places. A) P(T 54.05) B) P(T > 19.70) C) P(23.45 T <62.90) D) The response times that enclose the central86% of the distribution are: Note:Round your answers to two decimal places for these next twoproblems.
    Low: to High: minutes

E) Obviously, the quicker the response time the more likely apatient is to survive. In fact, response times falling at or belowthe 2.9 percentile are accompanied by survival rates of 93 %. Theresponse time that marks the 2.9 percentile is: minutes A) P(T 54.05) B) P(T > 19.70) C) P(23.45 T <62.90) D) The response times that enclose the central86% of the distribution are: Note:Round your answers to two decimal places for these next twoproblems.
