One-hundred and twenty subjects participated in the experiment, Sixty men and sixty women, were given the “water-level task” to test their perceptual and conceptual skills. Subjects were shown a drawing of a glass titled at a 45 degree angle. They were then asked to draw a line representing the surface of the water. The researchers recorded whether or not the line drawn was within 5 degrees of the true line. These are the results of people who were within the 5 degrees. Are the proportions the same?
| x | n | |
| Women | 24 | 60 |
| Men | 39 | 60 |
Apply a two-sided hypothesis procedures to test for a difference in proportions.
