You have been asked to study the characteristics of currently available fragrances so the company will be in a better position to price its proposed new product. You have collected data for 95 products on the market. The data is on an excel file named "FRAGRANCE".

Questions: Part 1) Provide a description of the data (for all the 95 products together) and show what Mean, Standard Deviation, Coefficient of Variation mean in this context.What conclusions can you draw from these measures? Part 2)Calculate the Mean, Median, Mode, Standard Deviation, Coefficient of Variation, 95% confidence interval for means for: o Prices for gender - male and female. o Prices for fragrance - perfume and cologne. o Prices for intensity - strong, medium and mild. o Prices for different countries – France, USA and other. What conclusions can you draw from these analyses? Also comment on the shape of distributions. Part 3)You are also required to answer the following questions (For one-sided tests, use the question of interest as the alternative hypothesis): 1.
