In а mоuntаinоus regiоn renowned for its winter sports, аvalanche safety is a top priority. A team of safety experts has been diligently recording the number of avalanches occurring at various locations over a 5-year period. The study differentiates between the Upper Mountain Range and the Lower Mountain Range. Compute a 5% trimmed mean for Upper Mountain Range and Lower Mountain Range. Round your answer to the nearest thousandth. For Upper Mountain Range: Number of avalanches at specific points 12 13 11 11 13 14 14 17 13 11 13 For Lower Mountain Range: Number of avalanches at specific points 16 11 11 0 14 15 12 20 13 0 11 19 12 11
