Test: Test 2 Submit Test This Question: 6 pts 18 or 24 (23 complete) This Test: 41 pts possible Based on data from a car bumper sticker study, when a car is randomly selected, the number of bumper stickers and the corresponding probabilities are as shown below Complete parts (a) through (d) 0 (0.791), 1 (0.095), 2 (0.034), 3 (0.028), 4(0014),5(0.011) 6 (0.009) 7 (0 008) 8 (0 006), 9 (0 004) a. Does the given information describe a probability distribution? O Yes No b. Assuming that a probability distribution is described, find its mean and standard devlation The mean is (Round to the nearest tenth as needed ) The standard deviation is Round to the nearest tenth as needed) c. Use the range rule of thumb to identify the range of values for usual numbers of bumper stickers The maximum usual value is Round to the nearest tenth as needed ) The minimum usual value is (Round to the nearest tenth as needed ) Click to select your answer(s) okExplanation / Answer
