We discussed the fact that measuring the same thing twice (or more) often yields somewhat different results, even if the thing being measured hasn't changed (think of measuring the size of a room, for example). That led us to suggest that the Observed score = True score + an Error term O there is no such thing as an accurate score O the Observed score must actually equal the True score O we have to make a correction for guessing when we need to measure carefully none of the above

Problem: customers are complaining about the sandwich length Interpret the results of the statistics:
An instructor for a test preparation course claims that the course will improve the test scores of students. The table shows the critical reading scores for 14 students the first two times they took the test. Before taking the test for the second time, the students took the instructor's course to try to improve their critical reading test scores. At a = 0.01, is there enough evidence to support the instructor's claim? Complete parts (a) through (f).
