    A 3-dimensional surface contains a saddle point when the point is a global minimum along a line parallel to either the x or the y axis, but a global maximum along the other axis. You'll usually see a "U" shape meeting an upside-down "U" shape. The classic horseback riding saddle has one such saddle point, and, not coincidentally, it is a rider's most stable position The input will be a 2-dimensional array AInIn] of numbers, representing a lattice approximation of...

    Use Table 8.1, a computer, or a calculator to answer the following. Suppose a candidate for public office is favored by only 47% of the voters. If a sample survey randomly selects 2,500 voters, the percentage in the sample who favor the candidate can be thought of as a measurement from a normal curve with a mean of 47% and a standard deviation of 1%. Based on this information, how often (as a %) would such a survey show that...
