NORMAL DISTRIBUTION 1. Find the distribution: a. b. c. d. e. f. following probabilities‚ the random variable Z has standard normal P (0< Z < 1.43) P (0.11 < Z < 1.98) P (-0.39 < Z < 1.22) P (Z < 0.92) P (Z > -1.78) P (Z < -2.08) 2. Determine the areas under the standard normal curve between –z and +z: ♦ z = 0.5 ♦ z = 2.0 Find the two values of z in standard normal distribution so that: P(-z < Z < +z) = 0.84 3.

Tourism distribution channel is a system of intermediaries or middleman that facilitates the sale and delivery of tourism services from suppliers to consumers (Buhalis and Law‚ 2001). Distribution channels can serve as part of the marketing mix that can makes the products available to consumers as the link between suppliers of tourism products and their end consumers‚ as well as the bridge between supply and demand (Kracht and Wang‚ 2010). This shows that‚ important to have a good distribution channel

supply chain evolution is characterized by both increasing value added and cost reductions through integration. A supply chain can be classified as a stage 1‚ 2 or 3 network. In a stage 1–type supply chain‚ systems such as production‚ storage‚ distribution‚ and material control are not linked and are independent of each other. In a stage 2 supply chain‚ these are integrated under one plan and is ERP enabled. A stage 3 supply chain is one that achieves vertical integration with upstream suppliers

Normal Distribution Normal distribution is a statistics‚ which have been widely applied of all mathematical concepts‚ among large number of statisticians. Abraham de Moivre‚ an 18th century statistician and consultant to gamblers‚ noticed that as the number of events (N) increased‚ the distribution approached‚ forming a very smooth curve. He insisted that a new discovery of a mathematical expression for this curve could lead to an easier way to find solutions to
