Vandenberghe January 4‚ 2006 Chapter 2 Convex sets Exercises Exercises Definition of convexity 2.1 Let C ⊆ Rn be a convex set‚ with x1 ‚ . . . ‚ xk ∈ C‚ and let θ1 ‚ . . . ‚ θk ∈ R satisfy θi ≥ 0‚ θ1 + · · · + θk = 1. Show that θ1 x1 + · · · + θk xk ∈ C. (The definition of convexity is that this holds for k = 2; you must show it for arbitrary k.) Hint. Use induction on k. Solution. This is readily shown by induction from the definition of convex set. We illustrate the idea for k = 3‚ leaving

past experience‚ and‚ therefore‚ by the establishment of a perceptual set. It is based on an experiment conducted by Bugelski and Alampay (1961). It was hypothesized that interpretation of an ambiguous stimuli that can be perceived as either a rat or a human face will be influenced by the context under which they view the figure and their past experience with other figures. That is they will be influenced by their perceptual set. The results from this study supported the hypothesis with the

Recently a number of studies‚ keeping this theorem in mind have

from the samples so that one can make inferences or extrapolations from the sample to the population. This process of collecting information from a sample is referred to as sampling. A complete sample is a set of objects from a parent population that includes ALL such objects that satisfy a set of well-defined selection criteria. For example‚ a complete sample of Australian men taller than 2m would consist of a list of every Australian male taller than 2m. But it wouldn’t include German males‚ or
