estimation will be done through a regression analysis. This analysis will examine the elements that management should look at when determining demand for a product such as: price‚ competitor’s price‚ customer income‚ advertising and the cost of microwave ovens. The main objective of this paper will be to: estimate the demand function using regression analysis‚ find elasticities of demand with respect to various variables and make forecasting decisions based upon the values of elasticities.

October 17 & October 24‚ 2012 How is Aspirin Made? This lab is about synthesizing aspirin using a hotplate to heat the reaction. It involved vacuum filtration‚ recrystallization‚ and comparing the properties of aspirin with salicylic aspirin. The first thing we did in this lab was make a hot-water bath by putting a beaker with water on a hot plate. After measuring out 2.1 grams of salicylic acid and 3 ml of acetic anhydride‚ we mixed the two together‚ along with 3 drops of sulfuric acid. We

microwavable popcorn is the most common way people make popcorn. The lab team has been hired by consumer reports magazine to help determine which brand of microwave popcorn is the “best”. Two different brands will be compared out of the many. These two brands of popcorn are Pop Secret and Pop Weaver. Pop Secret is a better brand of microwave popcorn‚ because it has been around longer‚ and it is a better known brand with a good reputation. Materials: 1 bag of pop secret 1 bag of pop weaver

Effect of Temperature on Salt Diffusion Rates and it’s Relation to the Human Body Hypothesis: Ordinary table salt is known to dissolve easily in water. Dissolving or diffusion is the spreading of particles in another substance. This is seen when smoke from a chimney diffuses in the air around it‚ or when dropping coloring in water. When NaCl‚ sodium chloride‚ or otherwise known as ordinary table salt is combined with water the separate salt and water molecules will be attracted to each other
