Hudson Group is a one of the largest and most
recognizable travel retailers in North America. we own and manage
over 1,000 duty-paid and duty-free stores in 89 locations,
including airports, commuter terminals, hotels and some of the most
visited landmarks and tourist destinations in the world.
In 2019 we initiated the Hudson Next Project, one of the key
pillars being the completion of design and implementation of four
new brands within the current Business Operating Model.
These brands include: Speciality stores, Newsstands, Book stores
& Brook stone stores
The new Specitity stores will be based out of the LAX airport. They
will cost approximately $19 million to contruct and will require
approximately 50 employees to operate. The Newstands, located in
Newark, New Jersey, will be based out of the airport - less than 15
miles outside of New York City, will cost $6.5 million to construct
and 20 employees to operate. The bookstores, located in Houston,
will require $8 million to construct and 15 employees to operate.
Located in the suburbs of Pittsburgh, Pennsylvania, the new
Brookstones stores will cost $12 million to construct and 50
employees to operate across all stores.
Hudson Group will pledge 75.5 million in new construction and hire
no more than 260 employees. Annually, Specialty stores are a 9.5
million operation, Newstands are a $2.4 million operation,
bookstores are a 1.2 million operation and the new Brookstones
stores net 3.3 million in volume and growing.
If Hudson Group wasnts to maximize it’s annual revenue, how many of
each for brands should they build?

ANOVA and Regression Projects
A national distributor of "Eagle" brand snacks is attempting to develop a model to explain sales of their product. To do so, data have been gathered on monthly sales (measured in thousands of dollars) from its many marketing areas. From these, sixty observations have been selected at random.
The data reported on the data sheet are as follows:
Column #1 = Monthly sales in thousands of dollars per marketing area.
2 = Promotional budget for the sales area, in thousands of dollars.
3 = Median family income in the sales area, in thousands of dollars.
4 = Product recognition index, proportion of respondents to a marketing survey in the market
district that recognized the Eagle brand name (reported as a decimal value).
5 = Average retail price of product in dollars.
6 = Average retail price of leading competitor brand in dollars.
7 = A coded variable representing the advertising method employed in the sales area.
There are four levels of this categorical variable labeled A, B, C, and D as follows:
A = Sports Magazine only
B = Radio Sport Show Ads
C = TV Sports Show Ad
D = TV General Advertising
Simple Regression Project
Of particular interest to the company is the effect of advertising expenditures on sales, the effect their price has on sales, and the effect of the different package designs the company has been using on sales (note: the dependent variable is not unit sales but dollar sales reported in hundreds of dollars).
You will need to adjust your Excel spreadsheet file from the Anova Project to do the following:

Case Study 1: Food Poisoning
Background
The faculty and staff of Bristol High decided to hold one of their faculty meetings at Central Park one evening after school. The plan was to have a cookout and then proceed with the meeting after everyone had time to eat and relax. Many faculty and staff members brought family members to the picnic. Everything seemed to progress as planned, that is until later that evening. That’s when people began to get sick. Many of the faculty came down with a mysterious illness.
City officials were alarmed at the sicknesses and deaths, which seem to be associated with the event. They have promised a full investigation. Park managers said that most of the symptoms—such as dehydration, stomach cramps, nausea, and vomiting—seem to indicate some type of food poisoning; however, at this point they cannot be certain.
Even the waste-water treatment plant just a few hundred yards up river will have to submit a report on their procedures for water treatment. This is the first time anything like this has happened at the park and officials want to be sure that it does not happen again.
You are now part of a team of epidemiologists that have been called in to get to the bottom of this mystery. You will need to identify the cause of the disease and prevent any further outbreaks. Time is of the essence.
Information
The picnic started at 6:00 p.m. Tuesday evening at Central Park. The park is located by the Bristol River and contains several gazebos and picnic areas. The administration and faculty of Bristol High School organized the picnic as a relaxing event before their faculty meeting to be held after dinner. Many faculty and staff brought members of their family.
Mrs. Smith and Ms. Johnston arrived at 5:30 to set up. Mr. Albert was next to arrive to set up the grill. He brought his grill from home and had to take a few minutes to clean it off because it had not been used since last summer. Mr. Drake arrived next from the supermarket where he had picked up the hamburgers. After the charcoal was lit and aluminum foil was placed over the grills, Mr. Albert began to cook.
At 5:55, Mrs. Smith realized there was only one serving spoon. She left to get some more, returning about 30 minutes later. The other teachers waited for a while, but finally decided to start eating about 6:20.
When all of the food arrived there was a full menu that included baked beans, chicken, ham, green bean casserole, tuna casserole, cherry pie, pudding, potato salad, macaroni salad, corn, and hamburgers. Drinks included soda, water, coffee, and tea.
Mr. Drake was first through the line. He tried:
Ms. Cummings was next. She ate:
The third person through the line was Mr. Carlson. He ate:
Mrs. Albert was next in line. She sampled:
Mrs. Smith arrived at this time with more serving spoons. Mrs. Bell came at the same time. She was a little late because she had to be sure that her chicken was done.
Mrs. Wolfe went through the line next. She ate:
Next was Mr. Lewis, who ate:
The line became a little unorganized at this point and it is not clear who went through next. Mrs. Smith and Ms. Johnston were two of the last people through since they helped to serve.
Mrs. Smith ate:
Others in attendance included Mr. Harvey, Ms. Jackson, Mr. Dooley, Mrs. Jones, and Mrs. Darwin. A lot of the guests said they could not remember exactly what they ate, but Mr. Harvey, Mr. Dooley, Mrs. Jones, and Mrs. Bell all had hamburgers, baked beans, and macaroni salad.
Ms. Jackson and Mrs. Darwin had ham, baked beans, corn, and some pudding for desert.
Mrs. Cain, Mrs. Williams, Dr. Oakton, Mrs. Corning, and Mrs. Reid have not yet been interviewed. Some other staff members arrived just in time for the faculty presentations, which started at 7:45. These included Mrs. Robinson, Mrs. Brown, and Mrs. Wright.
Some of the faculty and staff walked around while they ate but most sat in one of the gazebos. The presentations were held in the main gazebo, which was a relief for some of the faculty because it seemed to be one of the few places free of duck droppings.
Even during the meeting, some of the kids chased ducks with their water guns. These kids never seemed to run out of water because the guns held almost a gallon each, but even if they did run out, they quickly refilled them from the river.
Just about everyone at the picnic except for those that came for the meeting only were soaked. Since it was a hot day, the only time anyone seemed to mind the soaking was when one of the kids missed their intended target and almost put out the grill. After this incident, which happened about 6:10, the kids stayed away from the main gazebo, where the food was located, and turned their attention to the ducks and teachers walking around.
Bristol High Picnic Menu

Potato salad: One jar of salad dressing, assorted diced vegetables, 2 tablespoons sugar, 1/2 cup mustard, 6 cups diced and cooked potatoes.
Macaroni salad: One box elbow macaroni, 3 T mustard, one jar salad dressing, various diced vegetables.
Tuna casserole: Cracker crust, 3 cans tuna, one can cream of mushroom soup, one can cream of chicken soup. Mixed and topped with parmesan cheese topping.
Hamburgers: Purchased at the supermarket just before the picnic (receipt showed time was 12:25).
Corn: 2 large cans of corn heated to simmering.
Cherry pie: Mountain top cherry pie, baked 40 minutes, pre-made.
Poisoned Picnic Faculty Information
Mrs. Cain
Brought plates and cups to the picnic. Had chicken, potato salad, pudding, green bean casserole. Became sick Tuesday evening. Symptoms included nausea, vomiting, and dizziness.
Mr. Lewis
Organized a game of volleyball set up by the gazebo. The players were a favorite target for the water guns!!! The only foul was when Mrs. Cain stepped on a duck going after the ball. Mr. Lewis became ill Tuesday evening. He was treated and released from the hospital Wednesday morning.
Mrs. Williams
Recovering. Became ill Tuesday night and was rushed to the hospital by her husband. Her son enjoyed his water gun, dowsing teachers with river water. She loved the burgers made by Mr. Albert. She also tried some green bean casserole, chicken, and pudding. Her son did not become ill.
Mrs. Reid
Sampled a little bit of everything. She became ill Tuesday night and finally went to the hospital Wednesday morning. She complained of stomach cramps and nausea. Doctors quickly began an IV to help replenish lost fluids. She briefly went into a coma then slowly recovered.
Dr. Oakton
Recovering. Had a great time except for when she stepped in duck droppings, which seemed to be everywhere. She didn’t even mind being soaked. She tried a little bit of everything to eat.
Mr. Albert
Mr. Albert took control of the grill. Mr. Drake soon showed up with the hamburger meat and started making the burgers. Mr. Albert had some potato salad, green bean casserole, a hamburger, and pudding for desert. Mr. Albert became ill, suffering from numbness, disorientation, nausea, and vomiting. He was treated and released after several days in the hospital.
Mrs. Corning
Arrived late, just in time to grab a burger and some green bean casserole. Most of the utensils and food were already put away. She became ill Wednesday morning and had to leave work around 8:30. She suffered from nausea, dizziness, and was so disoriented that she could not drive home.
Mrs. Smith
She arrived early with her son and helped to set up for the picnic. After many of the staff arrived, she realized that there was only one serving spoon so she went home to get some more. She returned about 30 minutes later with spoons, (after several faculty had gone through the line) to find her son chasing ducks with the water guns. Both Mrs. Smith and her son became ill.
Ms. Johnston
Helped to set up for the picnic. She had a hamburger, baked beans, pudding, and corn. She and several other teachers spent their time sitting in one of the gazebos talking and watching the children dash about after the ducks. Ms. Johnston is lactose intolerant. She became ill just a couple of hours after the picnic suffering from severe stomach pains. She went to bed and recovered overnight.
Mrs. Albert
Complained of stomach cramps early Tuesday night. Her condition continued to worsen until she finally had to be taken to the hospital. She was given massive doses of antibiotics. Her condition became worse as her symptoms began to include vomiting and disorientation. She soon found that she could not remember much about the picnic. After some time her condition improved.
Additional Information
We have since learned that luckily there was only one burger on the grill when it was soaked. Mr. Albert decided to throw it away because he had to lift up the grill and add more charcoal. Many times he would walk away from the grill to talk to someone and return to some very well done burgers. No one seemed to mind, that's the way they wanted them.
We have also learned that the wastewater treatment plant performed several tests on the water coming from their plant. The effluent (water being pumped out) was virtually void of any bacteria. The plant was doing a good job. They also did tests on the water around the park and found no notable bacterial contamination.
