urgently QUESTION 3Problem 1c:XYZ Corporation develops a wide range of products for its target market. Overall, 25% of its existing products are considered by the marketingdepartment to be successful (S) and 75% are unsuccessful.The company is using a panel of potential customers to evaluate existing product designs, with the objective to improve the success rate of futureproducts. Of the existing products, 80% of successful products (S) received good reviews (G), and 10% of unsuccessful products received goodreviews.The customer panel is also used to evaluate a number of new product designs, for which the marketing department has no data to determine if theproduct will be successful or not. Assume that the population of new product designs has the same probability distributions as those of the existingproducts. You are asked to determine: Of the new product designs that receive a good review, what proportion would be successful?(c) Of the alternatives given below, select the correct expression for this question.P(SUG) =O P(S) =O P(S|G) =P(SNG) =

For 25 years, Arthur Reynolds and Judy Temple tracked more than 1,400 children who participated in a publicly funded early childhood development program beginning at age 3. They found that children who participated in the program showed higher levels of educational attainment, socioeconomic status, and job skills, as well as lower rates of substance abuse, felony arrest, and incarceration, than those who did not receive school-based early education. One possible theory for the success of this program is that improving school readiness improved the children's success in school. The improved success in school in turn improved their readiness for adulthood, resulting in increased job skills and socioeconomic status as well as lower rates of substance abuse.

Suppose you have been employed by ALADIN Solutions Ltd. as an Operations Manager to study the efficiency of customer service center of SONE Bank in handling customers. The customer service center has two serving points, Alpha and Bravo, through which customers are catered. Your field survey results are presented in Table 1 as follows: Table 1: Wait time of Service Points in Minutes Customer No. Alpha Bravo 1 12 10 2 16 3 3 11 8 4 10 7 5 17 6 6 10 16 7 13 15 8 18 16 9 6 20 10 17 9 You are required to write a letter to your supervisor for presenting the results of your analysis. Use mean waiting times and box plots as the tools to compare the efficiency of Alpha and Bravo serving points. Assuming a customer visits Alpha and Bravo points and is handled in 18 minutes. Which point is handling customer better? Use Z-Score to determine this and incorporate the results in your letter.
Questions 4-5 deal with the following information: GloboSnax has an overall 10% success rate when introducing new products. (Suppose success here means a product achieves a certain target market share within 2 years of its introduction.) Before roll-out, a secret forecasting committee assesses each new product, and calls it a “winner” or “loser.” In the past, the committee has done reasonably well in distinguishing between successful and unsuccessful products: 90% of products that went on to succeed were correctly called “winners” by the committee. 70% of products that went on to fail were correctly called “losers” by the committee. A new product, CocoChips is evaluated and labeled a “winner” by the committee. 4. Based on the information available, calculate the probability that CocoChips will succeed, given the “winner” classification from the forecasting committee. (Hint: you can use a 2x2 table, and/or Bayes Rule formula to help compute your answer.) 5. What would be a…
Jointsoft is a great over-the-counter arthritis medication, but who will ever know about it? Unfortunately, many people with arthritis tend to be elderly and rather immobile, so advertisers of arthritis medications face limitations in ways to get their messages across. Currently, their best modes of advertisement are commercials on daytime TV, advertisements in select magazines, fliers in convalescent homes, and advertisements on certain Web pages. Marketing managers for Jointsoft are investigating these four modes of advertisement in four small communities (with a different mode of advertisement in each community). The marketing managers have selected 38 days at random and are looking at the daily sales (in dollars) in each of the communities on each of these days. Here is what they have to work with. Groups Sample size Sample mean Sample variance TV 38 573.0 1777.7 Magazines 38 554.3 2761.0 Fliers 38 584.0 2445.4 Web pages 38 587.3 2943.2

Chapter 1, Section 1, Exercise 019 Trans-Generational Effects of EnvironmentWe ask whether experiences of parents can affect future children and describe a study that suggests the answer is yes. A second study, described in the same reference, shows similar effects. Young female mice were assigned to either live for two weeks in an enriched environment or not. Matching what has been seen in other similar experiments, the adult mice who had been exposed to an enriched environment were smarter (in the sense that they learned how to navigate mazes faster) than the mice that did not have that experience. The other interesting result, however, was that the offspring of the mice exposed to the enriched environment were also smarter than the offspring of the other mice, even though none of the offspring were exposed to an enriched environment themselves. One variable is whether or not the young female mice lived in an enriched environment and another variable is how fast the offspring…
