The manufacturer of an airport baggage scanning machine claims it can handle an average of 560 bags per hour. (a-1) At a = .05 in a left-tailed test, would a sample of 16 randomly chosen hours with a mean of 538 and a standard deviation of 50 indicate that the manufacturer's claim is overstated? Choose the appropriate hypothesis. a. H₁: b. He: <560. Reject H₁ if tcalc> -1.753 <560. Reject He if tcalc > -1.753 c. H₁: 2 560. Reject H₁ if tcalc < -1.753 d. He: 2 560.
