The lsat assesses reading and verbal reasoning skills and, along with gpa, is considered a critical factor in determining admission to law school. Companies offer an lsat preparation (i. e. , training) course, for a fee, with the claim that graduates of their course on average obtain higher scores on the lsat than the general population of lsat test takers. To test this claim, you randomly sample 100 graduates of lsat training courses and find that, on average, those in the sample have higher lsat scores than the population of lsat writers as a whole. So instead, she has drawn a random sample, following the rule of epsem, of 100 graduates from records provided by the companies offering the lsat training course in canada. The canadian population of graduates of the lsat training course is also symbolized by a large circle because it is a sizable group, although only a fraction of the population of lsat writers as a whole.
