On the midnight shift, the number of patients with head trauma in an emergency room has the probability distribution shown below. X 1 2 3 4 5 Total P(x) . 01 . 40 . 29 . 18 . 10 . 02 1.00 (a) Calculate the mean and standard deviation. (Round your mean value to 2 decimal places and standard deviation to 3 decimal places.) Mean Standard deviationOxnard Petro Ltd. is buying hurricane insurance for its offcoast oil drilling platform. During the next ve years, the probability of total loss of only the above-water superstructure [$270 million] is .30. the probability of total loss of the facility {$970 million} is .30, and the probability of no loss is .40. Find the expected loss. {Input the amount as a positive value: Expected Loss $ :] million a. n = 55, TT =.90 (Round your mean value to 2 decimal places and standard deviation to 4 decimal places.)
