MY NOTES PRACTICE ANOTHER 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 car 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 distribution with a mean of 10.0 minutes and a standard deviation of 1.5 minutes. For a randomly received emergency call, find the following probabilities. (For each answer enter a number. Round your answers to four decimal places.) (a) the response time is between 7 and 11 minutes (b) the response time is less than 7 minutes c) the response time is more than 11 minutes Need Help? Rand I 17. [-/5.26 Points] DETAILS BBBASICSTAT8ACC 7.5.006.MI.S. MY NOTES PRACTICE ANOTHER Suppose x has a distribution with a mean of 80 and a standard deviation of 21. Random samples of size n = 36 are drawn. [a) Describe the x distribution. Ox has a normal distribution. O x has a binomial distribution. O x has a Poisson distribution. O x has an unknown distribution. O x has a geometric d O x has an approximately normal distribution. Compute the mean and standard deviation of the distribution, (For each answer, enter a number.) [b) Find the z value corresponding to > = 73. (Enter an exact number.) (c) Find P(x = 73). (Enter a number. Round your answer to four decimal places.) P(x = 73) = d) Would it be unusual for a random sample of size 36 from the x distribution to have a sample me s than 73? Explain Yes, it would be unusual because more than 5%% of all such samples have means less than 73. No, it would not be unusual because more than 5% of all such samples have means less than 73. D Yes, it would be unusual because less than 5% of all such samples have means less than 73. ( No, it would not be unusual because less than 5% of all such samples have means less than 73. Need Help?
