Question Let X1, X2,. . . , X100 denote the actual net weights of 100 randomly selected 50-lb bags of fertilizer. (Give answers accurate to 3 decimal places.) (a) If the expected weight of each bag is 50 and the variance of X is 1.3, calculate P(49.9 SX50.1) (approximately) using the CLT. (b) If the expected weight is 49.8 lb rather than 50 lb so that on average bags Let X1, X2,. . . , X100 denote the actual net weights of 100 randomly selected 50-lb bags of fertilizer. (Give answers accurate to 3 decimal places.) (a) If the expected weight of each bag is 50 and the variance of X is 1.3, calculate P(49.9 SX50.1) (approximately) using the CLT. (b) If the expected weight is 49.8 lb rather than 50 lb so that on average bags are underfilled, calculate P(49.9SXS 50.1)
