Using the preliminary data collected in the Topic 2 assignment, complete two hypothesis tests relevant to the specific requirements of your scenario. To ensure tests are not duplicated, collaborate with the other members of your group to identify specifically which data each person in the group will be utilizing in the hypothesis tests. For example, if you are comparing sports teams, one member of the group might compare the Tigers and the Rams, while another member of the group might compare the Sharks and the Eagles. Using Excel, complete the two hypothesis tests using different data sets at a .05 level of significance. Generate a box plot for each test. The accuracy of formulas and the box plot visuals will be assessed.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
