The packages mall faces following situation, their monthly sales statement indicates an increasement in sale every month. Thus, manager is able to assume, that the company will get net profit this year (based on the sales trend for the past few months), without obtaining other information such as operational cost, change of taste in consumers and environment influence. Therefore, the manager assign probability that the packages mall will obtain profits is 65% and assign the probability make losses is 35%. Based on these probabilities, the manager will make a decision to increase investment. Identify the decision-making condition, under which manager take decision? Give reasons

- It's a Machine Learning question. Suppose we have market basket data consisting of 100 transactions and 20 items. Compute the total number of possible association rules. If the support for item A is 25%, the support for item B is 90% and the support for itemset {A,B} is 20%. Let the support and confidence thresholds be 10% and 60%, respectively. Compute the confidence of the association rule {A} → {B} & {B} → {A}.Question 4 A university received 1000 applications for the undergraduate program every semester. Of all applicants, 150 had a CGPA score above 3.70. 520 applicants had a CGPA score between 3.50 and 3.70. 100 applicants had a score between 3.00 and 3.50. All other applicants had a score lower than 3.00. What probability will a randomly selected applicant have a score lower than 3.00? If this semester, the total of students who get the CGPA score lower than 3.00 is 20% of the total student received, and the number of the other students who get CGPA above 3.50 is the same. Find the number of students who get CGPA between 3.00 and 3.50?(An LP model for the blending problem) The Exxoff-Still Company must decide how different components of the raw materials are blended for their gasoline production. The characteristics of their two gasoline products are listed below: Gasoline Vaper Pressure Octane Number Selling price ($/barrel) Regular ≤7 ≥80 10 Premium ≤6 ≥100 12 The characteristics of the raw materials from which the gasoline can be blended are shown below: Raw Materials Vaper Pressure Octane Number Availability (barrels) Cat Gas 8 83 2700 IsoIso Gas 20 109 1350 Brady Gas 4 74 4100 The vapor pressure and octane number of a blend is simply the weighted average of the corre- sponding characteristics of its components (weighted by their proportion in the blend). (a) Please formulate a linear programming model to determine how different components of the raw materials are blended for their gasoline production to maximize Exxoff-Still’s total rev- enue. Be sure to clearly define all decision variables and explain the…
- Reviewing the past history of LIH applications, David estimated the probability that the application decision would be delayed beyond 60 days to be 20%. David then estimated that the probability that the outcome of the new proposal is favourable is 70%. Given that the outcome of the new proposal were favourable, David estimate that the probability of the LIH plan to be approved is 75%; if the outcome were unfavourable, the probability of approval is 30%. Finally, David estimated the probability that the property would still be available for purchase after the policy revision (if Real Estate took no action) to be 80%. David next went to work on the financial analysis of the development project. The estimated profit of the new development project under the LIH plan would be $850,000. This value includes the purchase cost of the property, the cost of renovations, annual maintenance costs, annual rental incomes, and applicable tax shelters. If LIH plan approval were not granted for the…Answer the question and justify it using a TRUTH TABLE. 1. Kim, Mina, and Yoo are all planning to have their booster shots tomorrow, but due to un- precedented circumstances, all of them cannot do it on the same day. So they decided who among them will receive their booster tomorrow considering their preferences. If Kim is hav-ing her booster shot then so does Mina. Either Mina or Yoo is having their booster shot but never both at the same time. Either Kim or Yoo or both are having their booster shots. If Kim will stay at home (i.e. she will have her booster shot on the other day) then so will Yoo. Who among them will have their booster shot/s tomorrow?Suppose you are working as a data scientist for an online retailer, and you are tasked with optimizing the pricing strategy for a new product. The product is currently priced at $50, but you want to determine whether a higher or lower price would result in greater profit. You estimate that the demand for the product can be modeled using a normal distribution with a mean of 100 units per day and a standard deviation of 20 units per day. The cost of producing each unit is $30, and the retailer's profit is the difference between the revenue and the cost. The retailer incurs a fixed cost of $1000 per day for operating expenses, regardless of the number of units sold. Use simulation to answer to the question.
- Global Logistics needs to rent space for storing product for the next three years. The following information regarding the demand and spot price is available. Current demand for the product is 150,000. Historically, Global Logistics has required 1500 square feet to store 1500 units of the product. Demand for the product can go up by 20% with a probability of 0.7 or down by 20% with a probability of 0.3. Global Logistics can sign a three-year fixed lease to rent 150,000 square feet of space at $1.00 per square foot per year. The firm may also choose to obtain warehousing space on the spot market. The current spot market price is $1.20 per square foot per year. The spot price can go up by 10% with a probability of 0.8 and can decrease by 10% with a probability of 0.2. The firm receives a revenue of $1.22 for each unit of demand. a) Create a decision tree showing period 0, 1 and 2 for the scenario described above. b) Calculate the NPV for the option when the firm decides to sign a…Consider values shown in the table below:i=1 (cold) i=2 (allergy) i=3 (stomach pain) p(Hi)0.60.30.1 p(E1 |Hi)0.30.80.3 p(E2 |Hi)0.60.90.0Those values represent (hypothetically) three mutually exclusive and exhaustive hypotheses for the patient’s condition. For example, H1: the patient has a cold, H2: the patient has an allergy, and H3: the patient has stomach pain with their prior probabilities, p(Hi)’s and two conditionally independent pieces of evidence (E1, patient sneezes and E2, patient coughs) which support these hypotheses to differing degrees. Therefore;a) Compute the posterior probabilities for the hypothesis if the patient sneezes. What is the conclusion that can be derived from this condition?b) Based on the answer from the previous result, as the patient coughs are now observed, compute the posterior probabilities for this condition. Explain the results.Assuming all Ghanaianswho are at least 18 years can choose between going to school or learning a trade.

- Teddy Bower is an outdoor clothing and accessories chain that purchases a line of parkas at $10 each from its Asian supplier, TeddySports. Unfortunately, at the time of the order placement, demand is still uncertain: Teddy Bower forecasts that its demand is normally distributed with a mean of 2100 and a standard deviation of 1200. Teddy Bower sells these parkas at $22 each. Unsold parkas have little salvage value; Teddy Bower simply gives them away to a charity (and also doesn’t collect a tax benefit for the donation). Round your answer to 2 digits after the decimal point if it is not an integer. Do NOT use comma in your numeric answers. Use excel for accuarate numbers. Dont round until the end. The probability that this parka turns out to be a “dog” is [xa]%, which is defined as a product that sells less than half of the forecast (use the standard normal table below). The underage cost is $[xb]. The overage cost is $[xc]. The critical ratio is [xd]. Teddy Bower should buy [xe] parkas…A chip company has two manufacturing plants. Plant A produces 40percent% of the chipsand Plant B produces 60percent% of the chips produced by the company. The company knows that 2percent% of the chips produced by plant A are defective and 1percent% of the chips produced by plant B are defective. If a randomly chosen chip produced by the company is defective, what is the likelihood that the chip came from plant A? a. 0.02×.4/(.02×.4)+(.01×.6) b. 0.01×.6/(.02×.4)+(.01×.6) c. 0.02×.6/(.02×.6)+(.01×.4) d. 0.01×.4/(.02×.6)+(.01×.4)
