1. A random sample of male college students who had tried out for the varsity basketball team yielded the following height scores, inches: 68, 72, 76, 70, 69, 73, 74, 70, 78, 70. If the population for adult males yields a parameter mean of 69, could this sample be representative of the known population? 2. In an attempt to test for the horizontal-vertical illusion (where the vertical line should be perceived as being longer than a horizontal line of equal length), a random sample of college freshmen was selected and asked to judge the length of a vertical line (line b) after having been told that the width of the horizontal line (line a) was 5 inches. The estimates (in inches) were as follows: 7, 7, 9, 6, 7, 7, 8, 6, 6. Tess the hypothesis at the .05 level that the illusion occurred. b Horizontal-Vertical Illusion a
