Question

Transcribed Image Text:The authors of the paper "Statistical Methods for Assessing Agreement Between Two Methods of Clinical Measurement" compared two different instruments for measuring a subject's ability to breathe out
air.+ (This measurement is helpful in diagnosing various lung disorders.) The two instruments considered were a Wright peak flow meter and a mini-Wright peak flow meter. Seventeen subjects
participated in the study, and for each subject air flow was measured once using the Wright meter and once using the mini-Wright meter.

(a) Suppose that the Wright meter is considered to provide a better measure of air flow, but the mini-Wright meter is easier to transport and to use. If the two types of meters produce different
readings but there is a strong relationship between the readings, it would be possible to use a reading from the mini-Wright meter to predict the reading that the larger Wright meter would have
given. Use the given data to find an equation to predict y = Wright meter reading using a reading from the mini-Wright meter. (Round your values to four decimal places.)
ŷ =
(b) What would you predict for the Wright meter reading of a subject whose mini-Wright meter reading was 584? (Round your answer to three decimal places.)
(c) What would you predict for the Wright meter reading of a subject whose mini-Wright meter reading was 391? (Round your answer to three decimal places.)
