Part A: Describe changes in patterns of drug abuse in the United States since the 1960’s. In your discussion, choose two drugs (one legal, one illegal) and discuss specific changes in use patterns over time. Discuss the impact (e.g., social, cultural, financial, etc.) of these changing patterns on society.

1. The Howell’s decided to build a resort hotel on land owned by Chief Ugundi. For each of the following items, indicate whether the cost should be recorded as Land (L), Land Improvements (LI), Resort Hotel (RH), or Equipment (E) by placing the correct answer in the space provided. Answer Fences around the property site cost $50,000 Construction of the resort hotel cost $5,000,000 Demolition of existing huts on the land cost $80,000 Installation of wooden sidewalks between the resort hotel and parking lot cost $40,000 Architectural fees for the resort hotel cost $30,000 A construction permit obtained from Chief Ugundi cost $20,000 Clearing the brush and removing unwanted trees on the site cost $60,000 Purchased a wagon to assist with hauling away trees and dirt for $25,000 The Professor charged $40,000 to act as engineer and architect on the resort hotel Constructing permanent tiki torches around the site as lighting cost $10,000 Landscaping (shrubs and decorative ornaments) around the resort cost $100,000 The actual purchase price for the land cost $200,000

Science has been recognized as a critical input in good decision making for park managers. How does the use of science benefit park management decisions?

You are the revenue manager of a 200-room hotel in Memphis. The management controllable costs (variable room costs) incurred when selling 1 room are $50. You are interested in evaluating hotel performance for two scenarios: fixed pricing and differential pricing.

Scenario one is that you used a fixed pricing strategy: at a selling pricing $200 per night your hotel would sell 150 rooms on a given day.

Scenario two is that you implement a three-price strategy: low rate $150 per night, regular rate $200 per night, and high rate $250 per night. Your hotel would sell 100 low-priced rooms, 60 regular-priced rooms, and 20 high-priced rooms per day.

2. Discuss which scenario generates more revenue for your hotel and why?

4. Leslie has been tasked with putting together a statistical report regarding the use of a particular park in her hometown. Previous data shows that 72% of the residents living in the town visited the park in the last month. She wants to know the probability that more than 98 individuals in a random sample of 150 residents have visited the park in the last month. Please Answer A-C

(a) Based on the information given, is the sample proportion p̂ of residents who have visited the park in the last month approximately normally distributed? Check the appropriate conditions to justify your answer

(b) What is the sample proportion p̂ for Leslies sample of 150 residents? Round your answer to two decimal places?

(c) What is the probability that more than 98 individuals in the random sample of 150 residents have visited the park in the last month?

In an article in the Journal of Advertising, Weinberger and Spotts compare the use of humor in television ads in the United States and in the United Kingdom. Suppose that independent random samples of television ads are taken in the two countries. A random sample of 400 television ads in the United Kingdom reveals that 145 use humor, while a random sample of 500 television ads in the United States reveals that 124 use humor.

(a) Set up the null and alternative hypotheses needed to determine whether the proportion of ads using humor in the United Kingdom differs from the proportion of ads using humor in the United States.

H₀: p₁ − p₂ (Click to select)≠= 0 versus H_a: p₁ − p₂ (Click to select)=≠ 0.

(b) Test the hypotheses you set up in part a by using critical values and by setting α equal to .10, .05, .01, and .001. How much evidence is there that the proportions of U.K. and U.S. ads using humor are different? (Round the proportion values to 3 decimal places. Round your answer to 2 decimal places.)
