Extracted text: The deflection temperature under load for two different types of plastic pipe is being investigated. Two random samples of 15 pipe specimens are tested, and the deflection temperatures observed are as follows (in oF): Туре 1: 206, 188, 205, 187, 194, 193, 207, 185, 189, 213, 192, 210, 194, 178, 205. Туре 2: 177, 197, 206, 201, 180, 176, 185, 200, 197, 192, 198, 188, 189, 203, 192. 1. Determine the coefficient of dispersion of each type of plastic pipe. 2. Interpret the results. Compare the SDUS of the 10th observation in each type. What conclusion can you make?
