1) A carpenter has accumulated a large collection of nails, screws and bolts, which he had randomly thrown together into a bucket. Later he wanted to estimate how many of each he had. To do this he grabbed a handful from the bucket. His results are shown below. Sample # 1 2 3 4 5 6 7 nails 19 18 19 19 18 20 22 screws 20 19 20 22 20 20 21 bolts 19 20 21 21 21 21 22 Based on the information presented can you infer anything about the relationship between the number of nails,screws and bolts in the bucket? Because of the very small discrepancy in the quantities it is unlikely any deduction can be made about the number of nails,screws or bolts in the bucket.
