The manufacturer of an airport baggage scanning machine claims it can handle an average of 553 bags per hour. (a-1) At α = .05 in a left-tailed test, would a sample of 16 randomly chosen hours with a mean of 533 and a standard deviation of 47 indicate that the manufacturer’s claim is overstated? Choose the appropriate hypothesis. H1: μ < 553. Reject H1 if tcalc > –1.753 H0: μ < 553. Reject H0 if tcalc > –1.753 H1: μ ≥ 553. Reject H1 if tcalc < –1.753 H0: μ ≥ 553. Reject H0 if tcalc < –1.753 b a d c (a-2) State the conclusion. tcalc = –1.702. There is not enough evidence to reject the manufacturer’s claim. tcalc = –1.702. There is significant evidence to reject the manufacturer’s claim. b a
