HW1 Answer Key 8-2. The number of observation n = 64 The number of intervals 8 n = = Starting point = 32.0, Ending point = 38.0 The width of each interval is (38-32)/8 = 0.75 Class Interval Frequency 32 = x < 32.75 4 32.75 = x < 33.5 5 33.5 = x < 34.25 14 34.25 = x < 35 16 35 = x < 35.75 12 35.75 = x < 36.5 4 36.5 = x < 37.25 5 37.25 = x < 38 4 37.625 36.875 36.125 35.375 34.625 33.875 33.125 32.375 15 10 5 0 C1 Frequency 4 5 4 12 16 14 5 4 8-2 Histogram Properties of the data: Shape: Unimodal (perhaps bimodal if you identify a secondary mode at ~37) Approximately Symmetric (This depends on how you define your intervals. Different selections can lead to graphs with different shape.) Location: ~34 Spread: ~6
