Beate Klingenberg manages a​ Poughkeepsie, New​ York, movie theater complex called Cinema 8. Each of the eight auditoriums plays a different​ film; the schedule staggers starting times to avoid the large crowds that would occur if all eight movies started at the same time. The theater has a single ticket booth and a cashier who can maintain an average service rate of

280 patrons per hour. Service times are assumed to follow a negative exponential distribution. Arrivals on a normally active day are Poisson distributed and average 200

per hour.

a) Find the average number of moviegoers waiting in line to purchase a ticket.
b) What percentage of the time is the cashier busy?
c) What is the average time that a customer spends in the system?
d) What is the average time spent waiting in line to get to the ticket window?
e) What is the probability that there are more than two people in the system? More than three people? More than four?

Cultural Diversity in the United States - Culture Shock: The Arrival of the Hmong

            Imagine that you were a member of a small tribal group in the mountains of Laos. Village life and the clan were all you knew. There were no schools, and you learned everything you needed to know from your relatives. U.S. agents recruited the men of your village to fight Communists, and they gained a reputation as fierce fighters. When the U.S. forces were defeated in Vietnam, your people were moved to the United States so they wouldn’t be killed in reprisal.

            Here is what happed. Keep in mind that you have never seen a television or newspaper and that you have never gone to school. Your entire world has been the village. They put you in a big house with wings. It flew. They have you strange food on a tray. The Sani-Wipes were hard to chew. After the trip, you were placed in a house. This was an adventure. You had never seen locks before, as no one locked up anything in the village. Most of the village homes didn’t even have doors, much less locks.

            You found the bathroom perplexing. At first, you tried to wash rice in the bowl of water, which seemed to be provided for this purpose. But when you pressed the handle, the water and the rice disappeared. After you learned what the toilet was for, you found it difficult not to slip off the little white round thing when you stood on it. In the village, you didn’t need a toilet seat when you squatted in a field to use the bathroom. When you threw water on the electric stove to put out the burner, it sparked and smoked. You became afraid to use the stove because it might explode. And no one liked it when you tried to plant a vegetable garden in the park.

            Your new world was so different that, to help you adjust, the settlement agency told you (Fadiman 1997):

To send mail, you must use stamps.

The door of the refrigerator must be shut.

Do not stand or squat on toilet since it may break.

Always ask before picking your neighbor’s flowers, fruit or vegetables.

In colder areas you must wear shoes, socks and appropriate outer wear. Otherwise, you may become ill.

Always use a handkerchief or a tissue to blow your nose in public places or inside a public building.

Picking your nose or ears in public is frowned upon in the United States.

Never urinate in the street. This creates a smell that is offensive to Americans. They also believe that it causes disease.

To help the Hmong assimilate, U.S. officials dispersed them across the nation. This, they felt would help them to adjust to the dominant culture and prevent a Hmong subculture from developing. The dispersal brought feelings of isolation to the clan and village based Hmong. As soon as they had a chance, the Hmong moved from these towns scattered across the country to live in areas with other Hmong, the major one being in California’s Central Valley. Here they renewed village relationships and helped one another adjust to the society they had never desired to join.

Please answer the following questions:

Do you think you would have reacted differently if you have been a displaced Hmong?

Why did the Hmong need one another more in the U.S. neighborhoods to adjust to their new life?

What culture shock do you think a U.S. born 19 year old Hmong would experience if his or her parents decided to return to Laos?

Using the information in the chapter related to ethnicity in chapter six, was it wrong for the U.S. officials to separate the Hmong to “help” them assimilate?

Regarding language, do you believe the Hmong continued to communicate in their mother tongue (even if they already knew to speak English) either in their isolated places or when they arrived back to reunite in Central Valley California? Would American born Hmong use the mother tongue too, communicate in English, or both?

10. A researcher claims that the mean rate of individuals below poverty in the City of Chicago is below 17 %. Based on the data represented for the years 2005 – 2011, perform a hypothesis test to test his claim using a significance level of α = 0.10.

11. Would your conclusion change for question 10 if you used a significance level of α = 0.05? Explain.

12. A survey conducted at Chicago Public Schools (CPS) involving high school students on whether they had participated in binged drinking during the past month. Binge drinking was defined as 5 or more drinks in a row on one or more of the past 30 days.

a. From the sample data is there evidence that the proportion of students who participate in binge drinking is greater than 10%? Write a null and alternative hypothesis and perform an appropriate significance test using α=0.05.

b. Construct a 90% Confidence Interval for the population proportion. Does it support the same conclusion as in 12a? Explain.

What levels of pay and benefits should you offer?

An important element of the human resource function is the determination and administration of pay and benefits. Pay includes employees' base salaries, pay raises, and bonuses, and is determined by a number of factors such as characteristics of the organization, the nature of the job, and levels of performance. Employee benefits are based on membership in an organization (and not necessarily on the particular job held) and include sick days, vacation days, and medical and life insurance. It is important to link pay to behaviors or results that contribute to organizational effectiveness.

Read the case concerning one of the leading hotel chains in the world, The Four Seasons Hotels and Resorts. The Four Seasons has an excellent reputation for customer service and also for employee satisfaction. Afterwards, analyze the reasons behind this reputation.

In 2015, Four Seasons Hotels and Resorts was one of only 12 companies to be ranked one of the "100 Best Companies to Work For" every year since Fortune magazine started this annual list. The Four Seasons often receives other awards and recognition such as being named the "Best Hotel Group Worldwide" by Gallivanter's Guide and dominating Travel & Leisure's World's Best Awards Readers' Poll and Condé Nast Traveler's Readers' Choice Awards based on customers' responses. In an industry in which annual turnover rates are over 35%, the Four Seasons' is around 13%. Evidently, employees and customers alike are satisfied with how they are treated at the Four Seasons. Understanding that the two are causally linked is perhaps the key to the Four Seasons' success. As the Four Seasons' founder, Isadore Sharp said, "How you treat your employees is how you expect them to treat the customer."

The Four Seasons was founded by Sharp in 1961 when he opened his first hotel. It was called the Four Seasons Motor Hotel, located in a less-than-desirable area outside downtown Toronto. Whereas his first hotel had 125 inexpensively priced rooms appealing to the individual traveler, his fourth hotel was built to appeal to business travelers and conventions. It had 1,600 rooms, conference facilities, several restaurants and banquet halls, and an arcade of shops. Both styles of hotels were successful, but Sharp decided he could provide customers with a different kind of hotel experience by combining the best features of both kinds of hotel experiences—the sense of closeness and personal attention that a small hotel brings with the amenities of a big hotel to suit the needs of business travelers.

Sharp sought to provide the kind of personal service that would really help business travelers on the road—giving them the amenities they have at home and in the office, amenities they miss when traveling on business. The Four Seasons was the first hotel chain to provide bathrobes, shampoo, around-the-clock room service, laundry and dry cleaning services, large desks in every room, two-line phones, and around-the-clock secretarial assistance. While these are relatively concrete ways of personalizing the hotel experience, Sharp realized that how employees treat customers is just as, or perhaps even more, important. When employees view each customer as a unique individual with his or her own needs and desires, and empathetically try to meet these needs and desires and help customers overcome any problems or challenges they face and truly enjoy their hotel experience, a hotel can indeed serve the purpose of a home away from home (and an office away from office), and customers are likely to be loyal and highly-satisfied.

Sharp realized that for employees to treat customers well, the Four Seasons needed to treat its employees well. Salaries are relatively high at the Four Seasons by industry standards. Employees participate in a profit sharing plan, and the company contributes to their 401(k) plans. Four Seasons provides medical and dental insurance. All employees get free meals in the hotel cafeteria, have access to staff showers and a locker room, and receive an additional highly attractive benefit—once a new employee has worked for the Four Seasons for six months, he or she can stay for three nights free at any Four Seasons hotel or resort in the world. After a year of employment, this benefit increases to six free nights, and it continues to grow as tenure with the company increases. Employees like waitress Michelle De Rochemont love this benefit. As she said, "You're never treated like just an employee. You're a guest . . . You come back from those trips on fire. You want to do so much for the guest." The Four Seasons also tends to promote from within. For example, while recent college graduates may start out as assistant managers, those who do well and have high aspirations could potentially become general managers in fewer than 15 years. This promotion system helps to ensure that managers have empathy and respect for those in lower-level positions as well as the ingrained ethos of treating others (employees, subordinates, coworkers, and customers) as they would like to be treated. All in all, treating employees well leads to satisfied customers at the Four Seasons.

Superior Paver sued homeowners Pamela and Mark for $14,350 it claimed was still owed as extra work incurred in installing concreate pavers in the driveway of their residence. Pamela and Mark had previously paid the $45,000 contract price, and they counterclaimed for $60,500 for the reasonable cost of making the contractor’s work conform to the contract. The evidence established that Superior did not install a proper base of 3” to 4” of crushed limestone before installing the pavers as required by the contract, which caused the pavers to move creating gaps between the pavers and causing water to flow into the garage. To correct the problem the pavers needed to be removed and the area excavated and replaced with a crushed limestone base before, again, installing the pavers. Superior claimed it had substantially performed the contract as their performance resulted in a fully usable driveway, and, the proper remedy, if any, was the reduction of the market value of Pamela and Mark’s property due to any defective performance. Superior further asserted that the cost of redoing the entire job would be economic waste.

The result?

A franchisee owner (Owner) of a popular hotel chain was bound by their franchise agreement with Mega Hotel Inc (Mega). Part of Owner’s obligations included that Owner maintain their 60 room hotel to at least minimum quality assurance standards. Owner’s hotel failed five consecutive quality inspections over two years, with the inspector noting damaged guest rooms, burns in the bedding, and severely stained carpets. Mega canceled the franchise agreement. Owner sued Mega for wrongfully canceling the agreement (breach of contract).

Owner’s defense against Mega cancelling the franchise was the following. The bridge repairs on the road leading to the hotel had adversely affected the hotels ability to live up to the franchise agreement. Further, the repairs made it commercially impractical for Owner to live up to the franchise agreement. For reasons such as the inability of hotel staff to arrive on time and properly clean the rooms. Will Owner’s defense prevail?
