Question

Themanufacturer of an airport baggage scanning machine claims it canhandle an average of 530 bags per hour. (See Aviation Weekand Space Technology 162, no. 4 (January 24, 2005), p.42.)

Requirement 1:

At = .05 in a left-tailedtest, would a sample of 16 randomly chosen hours with a mean of 510and a standard deviation of 50 indicate that the manufacturer'sclaim is overstated? Choose the appropriate hypothesis.

Requirement 2:

Whymight the assumption of a normal population be doubtful? Theproblem arises when, (Check the appropriatebox(es))

H0: 530,reject H0 if t <-1.753 H0: < 530,reject H0 if t >-1.753 H1: 530,reject H1 if t <-1.753 H1: < 530,reject H1 if t >-1.753

Requirement 2:

Whymight the assumption of a normal population be doubtful? Theproblem arises when, (Check the appropriatebox(es))

too many bags are processed. low number of bags are processed. a perfect symmetric distribution willhappen. a skewed distribution will arise.

Explanation / Answer

Requirement 1: H0: 530,reject H0 if t
