(2+5=7 pts) Adding cоmputerized medicаl imаges tо а database prоmises to provide great resources for physicians. However, there are other methods of obtaining such information, so the issue of efficiency of access needs to be investigated. The results (in minutes) from an experiment in which 10 computer-proficient medical professionals were timed both while retrieving an image from a library of slides and while retrieving the same image from a computer database with a Web front end are listed below. T1 T2 T3 T4 T5 T6 T7 T8 T9 T10 T-bar s2 Slide 30 25 40 25 20 30 35 62 40 51 35.8 12.93 Digital 25 16 15 15 10 20 7 16 15 13 15.2 4.94 a. State any assumptions about the distribution of the data that are necessary to do part (b). b. Is there any evidence that the average time for retrieving an image is different when it is retrieved from a library of slides than when retrieved from a computer database? Use α=0.01. State the null and alternate hypotheses, compute the test statistic, give the rejection or fail-to-reject region(s), report the conclusion of the test, and interpret it.
