Consider again the scenario described in Problem 4.
The Center for Business Analytics is considering a refund policy for no-shows. No
refund would be given for members who do not attend, but nonmembers who do not attend will be refunded 50 percent of the price. Extend the model you developed in Problem 4 for the Business Intelligence Symposium to account for the fact that, historically, 25 percent of members who registered do not show and 10 percent of registered nonmembers do not attend. The Center pays the caterer for breakfast and lunch based on the number of registrants (not the number of attendees). However, the Center pays for parking only for those who attend.What is the profit if each corporate member registers their full allotment of tickets and 127 nonmembers register?
Use a two-way data table to show how profit changes as a function of number of registered nonmembers and the no-show percentage of nonmembers. Vary the number of nonmember registrants from 80 to 160 in…
Question 1A. Francophone is a telecommunication company, which is located in the Accra –Adabraka. The company sells mobile phones and accessories. Most of their newlyreleased phones are ordered. Francophone stocks three main phones for walk-incustomers. Every week, they generate profits of GH¢600 from selling Galaxy S2,GH¢400 from Galaxy S3 and GH¢300 from Galaxy S4. The overall weekly cost of thesetypes of phones are GH¢1,800, GH¢2,100 and GH¢1,200 respectively.This week, Francophone has a budget of GH¢12,000 available to buy these three types ofphones. During sales, each phone type must be unpacked, leading to 8 hours of unpackingtime for S2 phones, 12 hours for S3 phones and 16 hours for S4 phones. The managerestimates that he and his workers have 120 labour hours available to unpack the three typesof phones. He has enough space to order 20 phones this week. The manager also wants tostock at least twice as many S4 as S2 and S3 phones because S4 phones sell better.2a) Formulate a…
Problem 10.4. We continue with the situation in Problem 8.8. Assume
that the two sample sizes are nį = 19 and n2 = 12 and the two sample
variances are s = 0.81 and s = 0.49. Is there enough evidence that fam-
ilies from culled populations have a lower bunching intensity than families
from non-culled populations? Use a test of hypothesis at level a = 0.005.
Suppose that the two populations are normally distributed with equal vari-

- Problem: The restaurant of a 165-room year-round resort hotel depends entirely on its room quests for its revenue. Average annual room occupancy is 77%. On average, 3.6 people occupy each room in use. We know from past experience that 82% of the guests will eat breakfast, 27% will eat lunch, and 55% will eat dinner in the resort's dining room. The average checks per meal are: Breakfast Lunch $8.50 $12.25 $19.87 Dinner The restaurant is open every day of the year.

- Question 2 Quality Air Conditioning manufactures three home air conditioners: an economy model, a standard model, and a deluxe model. The profits per unit are $63, $95, and $135, respectively. The production requirements per unit are as follows: PLEASE ANSWER D to G . If there are two possible answers one will suffice. Where necessary a range analysis must be shown. a) The profit per unit for deluxe model was increased to 150 per unit. Evaluate the effect b) . Identify the range of optimality for each objective function coefficient (unit profit). Suppose the profit for the economy model is increased by $6 per unit, the profit for the standard model is decreased by $2 per unit, and the profit for the deluxe model is increased by $4 per unit.

Three factors appear to be related to regional sales: the number of retail outlets in the region, the total personal income of the region, and the number of cars registered in the region. The following table shows the data for 10 regions that were gathered for last year sales.

Ski Jacket Production. Egress, Inc., is a small company that designs, produces, and sells ski jackets and other coats. The creative design team has labored for weeks over its new design for the coming winter season. It is now time to decide how many ski jackets to produce in this production run. Because of the lead times involved, no other production runs will be possible during the season. Predicting ski jacket sales months in advance of the selling season can be quite tricky. Egress has been in operation for only three years, and its ski jacket designs were quite successful in two of those years. Based on realized sales from the last three years, current economic conditions, and professional judgment, 12 Egress employees have independently estimated demand for their new design for the upcoming season. Their estimates are listed in Table 15.2 To assist in the decision on the number of units for the production run, management has gathered the data in Table 15.3. Note that S…arrow_forward
- Question 6 The University of Dar es Salaam Silver Sands Hotel has a capacity of 20 rooms. From the historical data, the hotel coordinator estimated that approximately 0.15 of all confirmed reservations will turn out to be "no-shows". As a mitigation strategy to avoid idle rooms, the hotel accepts confirmed reservations for as many as 25 rooms. However, if more confirmed reservations arrive than there are rooms, the overbooked guests will have to be sent to a nearby hotel and given a complimentary dinner. Required If the hotel currently has 25 confirmed reservations, find a) the probability that no customers will be sent to another hotel b) the probability that exactly 2 guests will be sent to another hotel c) the probability that 3 or more guests will be sent to another hotelarrow_forwardRead the following scenario describing a research project, and then write a short criticism of this project. You should clearly identify at least four aspects of the project which you believe are incorrect or poor. These may relate to the research question, the experimental design, the analysis and reporting, and/or any ethical or academic misconduct issues. For each criticism which you identify, clearly describe the problem and state how it should have been addressed to improve the quality of the research.
