Answer #1

Solution - given that, U = 6.7 minutes 6=1.5 minutes ( 6 1.5 P(X<10:0) = P ( x-M < 10.0-6.7) - P(Z 22.2) using standard norma

    Mt. Brighton Ski Resort is looking at their response times for emergency calls at their resort. One variable of interest is the time it takes to respond to a call for ski patrol help. Let X be the continuous random variable that describes this time. Their last data gathering exercise showed that the average time was 5 minutes and the standard deviation was 1.5 minutes. Assume the distribution on time is Normal. 10% of emergency calls are responded within how...

    The taxi and takeoff time for commercial jets is a random variable x with a mean of 8.2 minutes and a standard deviation of 3.5 minutes. Assume that the distribution of taxi and takeoff times is approximately normal. You may assume that the jets are lined up on a runway so that one taxies and takes off immediately after the other, and that they take off one at a time on a given runway. (a) What is the probability that for...

    Police response time to an emergency call is the difference between the time the call is first received by the dispatcher and the time a patrol radios that it has arrived at the scene. Over a long period of time, it has been determined that the police response time has a normal distribut with a mean of 10.4 minutes and a standard deviation of 1.7 minutes. For a randomly received emergency call, find the following probabilities (For each answer, enter...

    Ann Perkins is concerned about ambulance response times in her neighborhood. She defines an "on-time response" as any emergency call in which an ambulance arrives within 3 minutes. She plans to obtain data from the city and compute the proportion of on-time responses in her neighborhood. She learns that the overall proportion of on-time responses in the city as a whole is 0.45. Let p represent the probability that an emergency call in her neighborhood has an on-time  response. Her null...
