Large companies typically collect volumes of data before designing a product, not only to gain information as to whether the product should be released, but also to pinpoint which markets would be the best targets for the product. Several months ago, I was interviewed by such a company while shopping at a mall. I was asked about my exercise habits and whether or not I'd be interested in buying a video/DVD designed to teach stretching exercises. I fall into the male, 18 – 35-years-old category, and I guessed that, like me, many males in that category would not be interested in a stretching video. My friend Diane falls in the female, older-than-35 category, and I was thinking that she might like the stretching video. After being interviewed, I looked at the interviewer's results. Of the 93 people in my market category who had been interviewed, 17 said they would buy the product, and of the 113 people in Diane's market category, 34 said they would buy it. Assuming that these data came…

- Describe the four levels of data measurement, and provide examples of when each method might be appropriate.arrow_forwardWhich model—the one for parliaments or the one for ministries (or cabinets)—presented in the article has the greater explanatory power? How can you tell?arrow_forwardBecause of safety considerations, in May 2003 the Federal Aviation Administration (FAA) changed its guidelines for how small commuter airlines must estimate passenger weights. Under the old rule, airlines used 180 pounds as a typical passenger weight (including carry-on luggage) in warm months and 185 pounds as a typical weight in cold months. A journal reported that an airline conducted a study to estimate average passenger plus carry-on weights. They found an average summer weight of 183 pounds and a winter average of 190 pounds. Suppose that each of these estimates was based on a random sample of 100 passengers and that the sample standard deviations were 15 pounds for the summer weights and 21 pounds for the winter weights. (a) Construct a 95% confidence interval for the mean summer weight (including carry-on luggage) of this airline's passengers. (Use technology to calculate the critical value.

- given this data, what will be the most appropriate way to present them?arrow_forwardThis problem does not require the use of data mining software and focuses on knowledge of concepts and basic calculations. The Boleyn sisters, a pair of entrepreneurs who recently sold their start-up for a multi-million-dollar sum, are looking for alternate investments for their newfound fortune. They are considering an investment in wine, similar to how some people invest in rare coins and fine art. To learn more about the properties of fine wine, they have collected data on 13 different characteristics of 178 wines. They have applied k-means clustering to these data for a range of k values and generated the following table of average silhouette values and elbow chart. k Average Silhouette Value 2 0.259 3 0.285 4 0.260 5 0.231 6 0.194 7 0.206 8 0.197 9 0.156 10 0.202 An elbow chart has a horizontal axis labeled "Number of Clusters" with values from 0 to 11 and a vertical axis labeled "Total Within-Cluster Sum of Squares" with values from 0 to 2,600.
