It is claimed that an equal number of men and women patronize a retail outlet specializing in the sale of jeans. A random sample of 40 customers is observed, with 25 being men and 15 being women. Test the null hypothesis that the overall number of men and women customers is equal by applying the chi square goodness of fit test using the 5 percent level of significance. Give your statistical decision and business decision for the above problem.

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
