Dear Expert

I need your perception and answers how to solve this problem

Pagliaci Pizza is developing a new frozen pizza product, and it asked a random sample of 30 customers to rate the product quality (x variable). The company also observed whether the customer bought the product at the end (y variable)

a. Write the estimated logistic regression equation relating x to y.

b. Based on the equation in part A), estimate the probability that a customer who gives a score of 90 points will buy the product.

c. Based on the equation in part A), a customer will have a 0.80 or higher probability of buying, what is the value of this score?

Simulation Case Study:
Phoenix Boutique Hotel Group

Phoenix Boutique Hotel Group (PBHG) was founded in 2007 by Bree Bristowe. Having worked for several luxury resorts, Bristowe decided to pursue her dream of owning and operating a boutique hotel. Her hotel, which she called PHX, was located in an area that included several high-end resorts and business hotels. PHX filled a niche market for “modern travelers looking for excellent service and contemporary design without the frills.” Since opening PHX, Bristowe has invested, purchased, or renovated three other small hotels in the Phoenix metropolitan area: Canyon Inn PHX, PHX B&B, and The PHX Bungalows.

One of the customer service enhancements Bristowe has implemented is a centralized, toll-free reservation system. Although many customers book specific hotels online, the phone reservation system enables PBHG to find the best reservation match at all properties. It has been an excellent option for those customers who have preferences regarding the type of room, amenity options, and the best price across the four hotel locations.

Currently, three agents are on staff for the 6 a.m. to 2 p.m. call shift. The time between calls during this shift is represented in Table 1. The time to process reservation requests during this shift is in Table 2.

Table 1: Incoming Call Distribution

Table 2: Service Time Distribution

Bristowe wants to ensure customers are not on hold for longer than 2 minutes. She is debating hiring additional staff for this shift based on the available data. Additionally, Bristowe and PBHG will soon be featured in a national travel magazine with a circulation of over a million subscriptions. Bristowe is worried that the current operators may not be able to handle the increase in reservations. The projected increase for call distribution is represented in Table 3.

Table 3: Incoming Call Distribution

Bristowe has asked for your advice in evaluating the current phone reservation system. Create a simulation model to investigate her concerns. Make recommendations about the reservation agents.

1. A taste-testing experiment has been designed so that four brands of Colombian coffee are to be rated by nine experts. To avoid any carryover effects, the tasting sequence for the four brews is randomly determined for each of the nine expert tasters until a rating on a 7-point scale (1=extremely unpleasing, 7=extremely pleasing) is given for each of the following four characteristics: taste, aroma, richness, and acidity. The following table displays the summated ratings-accumulated over all four characteristics.

1. State a null and alternative hypothesis to determine if a difference exists between four different brands for a parametric and a nonparametric test.
2. Check the necessary conditions.
3. Give your conclusion from both tests and a final conclusion. Use .

For many years, Lawton Industries has manufactured prefabricated houses where the houses are constructed in sections to be assembled on customers’ lots. The company expanded into the precut housing market in 2006 when it acquired Presser Company, one of its suppliers. In this market, various types of lumber are precut into the appropriate lengths, banded into packages, and shipped to customers’ lots for assembly. Lawton decided to maintain Presser’s separate identity and, thus, established the Presser Division as an investment center of Lawton.

              Lawton uses return on average investment (ROI) as a performance measure the investment defined as operating assets employed. Management bonuses are based in part on ROI. All investments in operating assets are expected to earn a minimum return of 15% before income taxes. Presser’s ROI has ranged from 19.3% to 22.1% since it was acquired in 2006. The division had an investment opportunity in the year just ended that had an estimated ROI of 18%, but Presser’s management decided against the investment because it believed the investment would decrease the division’s overall ROI.

              Presser’s operating statement for the year just ended is presented next. The division’s operating assets employed were $12,600,000 at the end of the year, a 5% increase over the balance at the end of the previous year.

Questions

1. Calculate these performance measures for the year just ended for the Presser Division of Lawton Industries:

1. Return on average investment in operating assets employed (ROI).
2. Residual income calculated on the basis of average operating assets employed.

2. Would the management of Presser Division have been more likely to accept the investment opportunity it had during the year if residual income were used as a performance measure instead of ROI? Explain your answer.

The Presser Division is a separate investment center with Lawton Industries. Identify and describe the items Presser must control if it is to be evaluated fairly by either the ROI or residual income performance measures

The most common abuse of correlation in studies is to confuse the concepts of correlation with those of causation.

Good SAT scores do not cause good college grades, for example. Rather, there are other variables, such as good study habits and motivation, that contribute to both. Find an example of an article that confuses correlation and causation.

Discuss other variables that could contribute to the relationship between the variables.
