An оrnithоlоgist would like to estimаte the meаn wingspаn of western screech owls in Southern California. The ornithologist studies a random sample of 10 western screech owls, measures the wingspan of each owl, and determines that the wingspans are normally distributed. The wingspans of these western screech owls (in centimeters) is provided below: [x1] [x2] [x3] [x4] [x5] [x6] [x7] [x8] [x9] [x10] Calculate the sample mean wingspan of the western screech owls. Round your answer to 3 decimal places.
