1. A company has two bottling machines both used to bottle juice. The machines pour juice into a bottle, and should pour exactly 345 ml of juice each time. The company needs to shut down and remove one of the machines and must decide which machine is operating the most efficiently and consistently. A sample of 15 juice bottles is chosen from each machine and the amount of juice is recorded. Machine A - 345, 342, 345, 346, 340, 342, 348, 345, 346, 344, 353, 347, 345, 344, 343 Machine B - 342, 340, 345, 348, 340, 341, 345, 347, 346, 348, 341, 351, 349, 345, 347 Decide which machine the company should keep by finding the mean and standard deviation for each bottling machine. Remember each machine should bottle 345mL of juice
