Vision Resort is a five-star resort and spa founded in 2012. Vision believes in offering authentic services to every customer by fulfilling and catering the needs of their guests efficiently. Facilities and services include spacious rooms, banquet halls, gardens, restaurants, a wide range of food with delicious cuisines. All its employees are well trained and provide high customer satisfaction.
Vision resort focuses on premium pricing strategy for its products as they cater to high profile business class and upper class of the society. The value provided through the luxurious experience to the customers during their stay in the resort and the first class royal service explains the high prices of the resort packages. However, in light of the current economic condition in the world due to the Coronavirus, the resort is currently trying to provide a combination of high quality and service while also providing fair prices.
Also, Vision resort is the owner and operator of the franchise system. They are present in 20 countries prominent ones being in Bahrain, Oman, Kuwait, and Dubai Chicago, Hong Kong, Manila, Mumbai, San Francisco, and Tokyo. It is noteworthy that the prices of the resort packages differ based on the geographic location. Also, prices fluctuate during different times of the year, as they tend to increase during the weekends and Eid holidays and decrease during the low seasons.
Regarding the promotion strategy, vision resort has built and maintained positive awareness, and brand value by word of mouth. This has been achieved by gaining high customer satisfaction and providing excellent customer relationship management. They reward loyalty to regular clients by their signature membership cards known as Vision Gold Passport accepted globally which fetches them extra discounts and additional perks. Due to the social distancing, vision resort adopted advertising via TV broadcasting. Moreover, digital marketing tools such as instagram sponsorship allowed reaching target customers through a click of a button.
Recently, a new global disease has spread rapidly among people and the resort decided to open its doors to the passengers arriving into the country by air and border crossings and were taken to stay for free in a 14-day coronavirus quarantine. This initiative shows the social responsibility that the resort holds towards the community.

Answer the following questions:
1. What is the major pricing strategy vision resort follows and why?
2. What is the price elasticity of demand for rooms in the resort and why?
3. What is the price adjustment strategy followed by the resort management?
4. Give examples of the promotion mix?
5. The hotel resort management is planning to open a new shop in the resort, a brain storming session was held with the hotel employees where they suggested the following ideas: A coffee shop, diving equipment shop, gifts shop. Explain the process (steps) undertaken by the resort management to introduce a new product.

Bramble Company owns 9,000 acres of timberland purchased in 2009 at a cost of $1,596 per acre. At the time of purchase, the land without the timber was valued at $456 per acre. In 2010, Bramble built fire lanes and roads, with a life of 30 years, at a cost of $95,760. Every year, Bramble sprays to prevent disease at a cost of $3,420 per year and spends $7,980 to maintain the fire lanes and roads. During 2011, Bramble selectively logged and sold 798,000 board feet of timber, of the estimated 3,990,000 board feet. In 2012, Bramble planted new seedlings to replace the trees cut at a cost of $114,000.

Determine the depreciation expense and the cost of timber sold related to depletion for 2011. (Round intermediate calculations to 5 decimal places, e.g. 1.54687 and final answers to 0 decimal places, e.g. 5,125.)

Bramble has not logged since 2011. If Bramble logged and sold 1,026,000 board feet of timber in 2019, when the timber cruise (appraiser) estimated 5,700,000 board feet, determine the cost of timber sold related to depletion for 2022. (Round intermediate calculations to 5 decimal places, e.g. 1.54687 and final answers to 0 decimal places, e.g. 5,125.)

the manager of an amusement park would like to be able to predict daily attendance in order to develop more accurate plans about how much food to order and how many ride operators to hire. after some consideration, he decided the following three factors are critical: 1. Yesterday's attendance 2. Weekday or Weekend 3. Predicted Weather He then took a random sample of 40 days. For each day, he recorded the attendance, day of the week, and weather forecast. The first independent variable is interval, but the other two are nominal. Accordingly, he created the following sets of indicator variables:

I1 = 1- (IF WEEKEND) 0 - (IF NOT)

I2 = 1 - (IF MOSTLY SUNNY IS PREDICTED) 2 - (IF NOT)

I3 = 1 - (IF RAIN IS PREDICTED) 2 - (IF NOT)

A. Conduct regression analysis

B. Is model valid? Explain

C. Can we conclude weather is a factor in determining attendance

D. Do these results provide sufficient evidence that weekend attendance is, on average, larger than weekday attendance?  

I will attach data in another question

#1. [Water Slide & Swing] You are designing a slide for a water park. In a sitting position, park guests slide a vertical distance h down the water slide, which has negligible friction. When they reach the bottom of the slide, they grab a handle at the bottom end of a 6.00-m-long uniform pole. The pole hangs vertically, initially at rest. The upper end of the pole is pivoted about a stationary, frictionless axle. The pole with a person hanging on the end swings up through an angle theta max , and then the person lets go of the pole and drops into a pool of water. Treat the person as a point mass. The pole’s moment of inertia is given by I = (1/3)ML , where L = 6.00 m is the length of the pole and M = 24.0 kg is its mass. In your design, a person of mass m = 70.0 kg is to have a maximum angle of swing of theta max = 72.0˚ after their collision with the pole.

(a) In the "collision" between the slider and the pole, why is angular momentum about the pole's pivot conserved, but linear momentum and kinetic energy are not conserved? Assume that the slider is moving horizontally when they grab the handle on the vertically hanging pole.

(b) What is the angular speed of rotation of the pole & swinger just after the swinger grabs on, in terms of the final height the swinger reaches?

(c) What is the speed of the swinger at the bottom of the slide just before reaching the pole, in terms of their speed just after grabbing the pole?

(d) For a person of mass m = 70.0 kg, what must be the starting height h in order for the pole with person to have a maximum angle of swing of theta max =  72.0˚ after the collision?

For questions 5 – 6, assume that to ride the Whirling Dervish at an amusement park, riders must be no taller than 75 in. Assume that men have normally distributed heights with a mean of 70 in. and a standard deviation of 2.8 in. 5. Find the percentage of men who will not meet the height requirement. Round to two percentage decimal places (for example, 38.29%). 6. If the height requirement is changed so that only the tallest 5% of men will be excluded from riding the Whirling Dervish due to height restrictions, what is the new height limit? Round to the nearest inch.

The following data show the length of the coasters at the Mega Park (x) and height of the same coasters (y). The regression equation for the data is given by y = 21.94 + 0.018x

a.      State and interpret the slope in the context of this problem, given the regression equation above.

b.      How tall does the linear regression model predict a coaster of 3450 feet long will be?

1. A politician wants to open a new park in the middle of town. She needs to make sure that the local community supports the plan. A nearby town recently found that 60% of the community supported a similar plan and she believes that the same proportion will support it in her district. She takes a random survey of 40 people and find that the 10 people are supportive of her plan. She wants to be certain that this is not just due to statistical error. She is going to use an alpha of .01 for her study.
