A company that sponsors LSAT prep courses would like to be able to claim that their courses improve scores by more than 3 percentage points. To te this, they take a sample of 8 people, have each take an initial diagnostic test, then take the prep course, and then take a post-test after the course. TH test results are below (scores are out of 100%): Person Initial Test Post-Test 1 68 66 72 73 3. 60 62 4. 76 81 73 79 6. 70 76 69 82 8. 68 68 Is there evidence, at an a = 0.065 level of significance, to conclude that the prep course improves scores by more than 3 percentage points? Carry c an appropriate hypothesis test, filling in the information requested. (Arrange your data so that the standardized test statistic is for the change from the initial test to the post-test.) A. What test method should be used? OA. Two Sample z OB. Matched Pairs C Two Sample t

It's true sand dunes in Colorado rival sand dunes of the Great Sahara Desert! The highest dunes at Great Sand Dunes National Monument can exceed the highest dunes in the Great - Sahara, extending over 700 feet in height. However, like all sand dunes, they tend to move around in the wind. This can cause a bit of trouble for temporary structures located near the "escaping" dunes. Roads, parking lots, campgrounds, small buildings, trees, and other vegetation are destroyed when a sand dune moves in and takes over. Such dunes are called "escape dunes" in the sense that they move out of the main body of sand dunes and, by the force of nature (prevailing winds), take over whatever space they choose to occupy. In most cases, dune movement does not occur quickly. An escape dune can take years to relocate itself. Just how fast does an escape dune move? Let x be a random variable representing movement (in feet per year) of such sand dunes (measured from the crest of the dune). Let us assume that…
