The catering manager of LaVista Hotel, Lisa Ferguson, is disturbed by the amount of silverware she is losing every week. Last Fridaynight, when her crew tried to set up for a banquet for 500 people, they did not have enough knives. She decides she needs to order some more silverware, but wants to take advantage of any quantity discounts her vendor will offer.

pieces or less) her vendor quotes a price of
$1.801.80/piece.
follows≻If
she orders
2 comma 0012,001
to
5 comma 0005,000
pieces, the price drops to
$1.601.60/piece.
follows≻5 comma 0015,001

and
follows≻10 comma 00110,001
and above reduces the price to
$1.251.25/piece.
Lisa's order costs are
$200200
per order, her annual holding costs are
55%,
and the annual demand is
44 comma 90044,900
pieces. For the best option (the best option is the price level that results in an EOQ within the acceptable range):
a) What is the optimum ordering quantity?
units (round your response to the nearest whole number).

A hotel wanted to develop a new system for delivering room service breakfasts. In the current system, an order form is left on the bed in each room. If the customer wishes to receive a room service breakfast, he or she places the order form on the doorknob before 11p.m. The current system requires customers to select a 15-minute interval for desired delivery time (6:30~6:45a.m., 6:45~7:00a.m., etc.). The new system is designed to allow the customer to request a specific delivery time. The hotel wants to measure the difference (in min.) between the actual delivery time and the requested delivery time of room service orders for breakfast (negative time means that the order was delivered before the requested time, whereas the positive time means that the order was delivered after the requested time). The factor included were the menu choice (American and Continental) and the desired time period in which the order was to be delivered (Early Time Period [6:30~8:00a.m.] or Late Time Period[8:00~9:30a.m.]). Ten orders for each combination of menu choice and desired time period were studied on a particular day, and the data were stored
| Type | Early | Late |
| Continental | 1.4 | -2.0 |
| Continental | 1.8 | 3.1 |
| Continental | 3.3 | -0.5 |
| Continental | 4.4 | 0.9 |
| Continental | 4.4 | 1.2 |
| Continental | 5.3 | -0.1 |
| Continental | 2.2 | -1.3 |
| Continental | 1.2 | 0.2 |
| Continental | 5.4 | -0.5 |
| Continental | 1.4 | 3.8 |
| American | 4.4 | 6.0 |
| American | 1.1 | 2.3 |
| American | 4.8 | 4.2 |
| American | 8.4 | 3.8 |
| American | 6.7 | 5.8 |
| American | 5.6 | 1.8 |
| American | 9.5 | 5.1 |
| American | 5.1 | 4.2 |
| American | 7.6 | 4.9 |
| American | 9.3 | 4.2 |
(a) At the 0.05 level of significance, is there an interaction between type of breakfast and desired time?
(b) Draw the plot of means.
(c) At the 0.05 level of significance, is there an effect due to type of breakfast?
(d) At the 0.05 level of significance, is there an effect due to desired time?

For this week's discussion, the focus will be on examining Porter's Five Forces as a tool for looking at the pressures on profits. Specifically, you will be looking at defining Porter's Five Forces and applying this tool to the market structures and pressures on profits of a chosen group of firms.
Choose one of the following groups and use Porter's Five Forces to analyze the pressures on profits for your chosen group's firms.
Group 1: the accommodations industry (e.g., Hilton, Marriott Bonvoy, Intercontinental Hotel Group).
Group 2: the wireless telecommunications industry (e.g., Verizon, AT&T, T-Mobile).

Gloucester Township Department of Public Works, in an effort to encourage use of its public parks during the summer months, began a campaign to encourage vacationers to use the parks. Studies for the past five years indicate that only one-fourth of all vacationers use the park for three days or more per week. A survey conducted after the new campaign was initiated reveals that 55 of 200 vacationers use the parks three or more days per week. At α = .05, does this support the campaign’s effectiveness?

Government allegation and prosecution of white collar crime is a major risk for corporations and management. Complying with all laws and regulations has never been more important.
(1) Criminal Liability explaining the two parts of a crime: the act or omission (actus reus) and the subjective state of mind (mens rea); (2) Individual Liability for Business Crimes explaining strict liability and the Park Doctrine. What are your thoughts about strict liability for corporate crimes? What does this mean for you as a corporate manager, officer, or director?

I planned on putting some math to work when I visited Golden Gate Park along with my new kite. I made sure my kite was always 100ft above the ground and I was able to calculate that the kite was moving horizontally at a speed of 9ft/s. Then I proceeded to calculate the rate at which the angle between the horizontal and the string was decreasing when I had let out about 250 ft of string. Can you help me determine what that rate was?

1) An earthquake centered in New Hampshire severely damages Fenway Park, forcing the Red Sox to have to build a new stadium. The team decides to construct its new facility in the nearby town of Quincy rather than in downtown Boston. Use the appropriate economic model to explain why it does so.
2) Referring to question #1, a politician in Massachusetts claims that the state must subsidize the construction of a new stadium because of the "positive externalities" that the team generates. Use the appropriate economic model to explain his reasoning.

A family on vacation in San Francisco drives from Golden Gate Park due south on 19th Avenue for 2.2 miles and then turns west on Sloat Boulevard and drives an additional 1.1 mile to go to the zoo. The driving time for this trip is 18 minutes. What is the family’s net displacement for this trip? What is the average speed for the trip? What is the average velocity? (Remember to specify the direction of the net displacement and the velocity vectors. This requires giving a reference, like “of the north”, and a direction the angle is measured, like “east” in the direction “20.0° east of north”.)
