Alaska's Katmai National Park celebrates fat bear week every year in the beginning of October, when brown bears are getting ready to go into hibernation. During the fat bear week, the public votes on bears to advance in the bracket through single-elimination rounds. Adult male bears regularly weigh around and even over 1000 pounds for their peak fall weights, while adult female bears generally weigh 1/3 less than the males. Suppose the weights of all ready-to-hibernate brown bears in the national park are distributed as shown in the following histogram. Weights of Bears 10 200 400 600 800 1000 1200 Weight in pounds The mean of all the peak fall bear weights is 695 pounds, and the standard deviation is 279 pounds. For a random sample of 30 bears, what is the probability of obtaining a sample mean less than 720 pounds? If the conditions to perform the necessary calculation are not satisfied, enter -1 instead. Give your answer accurate to four digits beyond the decimal point. Answer. Aouanba
