A sample of coarse aggregate is placed in a bucket of know volume (0.5 ft^3) and rodded with a tamping rod to determine its unit weight. The empty weight of the bucket is 20.3 lb. The weight of the bucket filled with dry aggregate was: Trial 1: 69.6 lb Trial 2: 68.2 lb Trial 3: 71.6 lb Trial 4: 70.8 lb Trial 5: 72.0 lb Based on the provided data determine the (i) average, standard deviation and coefficient of variance of the dry rodded unit weight; (ii) % voids of the aggregate sample if Gs = 2.620

Question
A sample of coarse aggregate is placed in a bucket of know volume (0.5 ft^3) and rodded with a tamping rod to determine its unit weight. The empty weight of the bucket is 20.3 lb. The weight of the bucket filled with dry aggregate was:
Trial 1: 69.6 lb
Trial 2: 68.2 lb
Trial 3: 71.6 lb
Trial 4: 70.8 lb
Trial 5: 72.0 lb
Based on the provided data determine the (i) average, standard deviation and coefficient of variance of the dry rodded unit weight; (ii) % voids of the aggregate sample if Gs = 2.620
