For a short time after a wave is created by wind, the height of the wave can be modeled using y - a sin 2piT/t, where a is the amplitude and T is the period of the wave in seconds. 13. Write an equation for the given function given the period, phase shift, and vertical shift. cotangent function, period =pi phase shift = -1/3 pi, vertical shift = 2

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.
