8. A hotel manager is looking to enhance the initial impression that hotel guests have when they check in. Believed to contribute to initial impressions is the time it takes to deliver a guest’s luggage to his or her room after check-in. A random sample of 20 deliveries on a particular day were selected from Wing A of the hotel, and a random sample of 20 deliveries were selected in Wing B (i.e., the Excel tab LUGGAGE). (a) Identify which type of test is most appropriate for you to use, justify your answer. (b) Determine whether or not the mean delivery time differs for the two wings of the hotel (use α = .05). (c) If faster luggage delivery time is positively related to guests’ initial impression, which wing(s) should receive the highest impression ratings? (3 points)

Emma has noticed a small red fox living in the park near her apartment. She takes a walk at the same time every day and has observed the fox in three different areas: in the woods, in the meadow, and by the pond.

If it is in the woods on one observation, then it is twice as likely to be in the woods as in the meadow on the next observation but not by the pond.

If it is in the meadow on one observation, then it is equally likely to be in any of the three locations on the next observation.

If it is by the pond on one observation, there is a 0.5 probability it will be by the pond on the next observation and will otherwise be in the woods.

When Emma went for a walk today, the red fox was in the woods.

a. Define the states and construct the transition matrix for this Markov chain.

b. Find the initial distribution vector for this Markov Chain.

c. Determine the probability that the red fox is in each of the three areas tomorrow.

If this trend continues, what is the probability the red fox will be in the meadow in the long run?

Twenty-three (24) states have made laws to allow medical marijuana usage and now more states (Colorado, New Jersey, Washington. Etc.) have legalized the recreational use of marijuana by adults. The legalization of Marijuana has been an ongoing debate in the United States. Many perspectives (some positive, some negative) have been presented in the press about the reasons for or against marijuana. The most pervasive argument against is that marijuana is a considered. Others concerns include potential drug addictions, increased crime rates, negative effects to the brain, etc... The American Psychological Association (APA) has posted a position paper titled, Medicine or Menace, which problematizes marijuana usage and legalization. For this weeks discussion, I want you to answer the following questions.

1. Should marijuana be legal or is its legalization a devastating mistake? Explain your stance with facts that are backed up by the book or other sources.

2. Do you think American culture is ready to effectively handle having marijuana legalization? Why or why not?

Application: Elasticity and hotel rooms.

The following graph input tool shows the daily demand for hotel rooms at the Big Winner Hotel and Casino in Las Vegas, Nevada. To help the hotel management better understand the market, an economist identified three primary factors that affect the demand for rooms each night. These demand factors, along with the values corresponding to the initial demand curve, are shown in the following table and alongside the graph input tool.

Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph.

Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly.

For each of the following scenarios, begin by assuming that all demand factors are set to their original values and Big Winner is charging $350 per room per night.

If average household income increases by 20%, from $50,000 to $60,000 per year, the quantity of rooms demanded at the Big Winner (Falls or Rises ) from ( ) rooms per night to ( ) rooms per night. Therefore, the income elasticity of demand is (Negative or Positive) , meaning that hotel rooms at the Big Winner are ( A normal good or An inferior good ).

If the price of an airline ticket from LAX to LAS were to increase by 20%, from $250 to $300 roundtrip, while all other demand factors remain at their initial values, the quantity of rooms demanded at the Big Winner (Falls or Rises) from ( ) rooms per night to ( ) rooms per night. Because the cross-price elasticity of demand is (Negative or Positive), hotel rooms at the Big Winner and airline trips between LAX and LAS are (Substitutes or Complements).

Big Winner is debating decreasing the price of its rooms to $325 per night. Under the initial demand conditions, you can see that this would cause its total revenue to (Decrease or Increase)  . Decreasing the price will always have this effect on revenue when Big Winner is operating on the (Elastic or Inelastic) portion of its demand curve.

Lab Text Manipulation

Inside the main method, do the following:

• Create an ArrayList of strings and call it parks.
• Read in the names of national parks from the user until the user enters done(or DONE,
  or dOnE, .. ) Keep in mind, that the names of some national parks consist of more than one word, for example, Mesa Verde.
  As you read in the national parks, add them to the list.
• Next, we are going to build a string based on the elements in the list parks. Since the text keeps changing as we add one park at a time, we use class StringBuilder for this task.
  • Use a StringBuilder called sb to create the string  nationalParks .
  • Loop through all the elements of the list  parks and add them one at a time.
    The resulting string should have the following format:
    Favorite National Parks: {park1} | {park2} | . . . | {parkN}
    The parks are separated by a space, a vertical bar, and another space. However, there is no vertical bar after the last element. {park1}, {park2}, {parkN} are the various list elements with updated spelling.
  • Create a private method to update the spelling.
    We can't control whether the user enters the park names in uppercase or lowercase letters. However, we can change the names to a spelling where all letters are lowercase except for the first letters of each individual word. In order to make those changes, create a private method called updateSpelling. It has the following method header:
    private static String updateSpelling(String text)
    E.g.: When you pass the string "MESA VERDE" the method returns "Mesa Verde"
    E.g.: When you pass "yEllOwstOnE" it returns "Yellowstone"
    E.g.: Passing "black canyon of the gunnison" returns "Black Canyon Of The Gunnison"
    E.g.: Passing "Denali" returns "Denali"
  • When you are done building the specified string in SringBuilder, print it.

The output depends on the information provided by the user.

Please enter your favorite National Park or DONE to stop: mesa verde
Please enter your favorite National Park or DONE to stop: black CANYON of ThE gunnisON
Please enter your favorite National Park or DONE to stop: DENALI

In​ baseball, League A allows a designated hitter​ (DH) to bat for the​ pitcher, who is typically a weak hitter. In League​ B, the pitcher must bat. The common belief is that this results in League A teams scoring more runs. In interleague​ play, when League A teams visit League B​ teams, the League A pitcher must bat.​ So, if the DH does result in more​ runs, it would be expected that league A teams will score more runs in League A park than when visiting League B parks. To test this​ claim, a random sample of runs scored by league A teams with and without their DH is given in the accompanying table. Complete parts​ a) through​ d) below.

a) Draw​ side-by-side boxplots of the number of runs scored by League A teams with and without their DH. Choose the correct graph below.

A.

Does there appear to be a difference in the number of runs between these​ situations?

A. No but the number of runs scored in a League A park appear to be slightly higher than the number of runs scored in a League B park.

B. Yes because the number of runs scored in a League B park appear to have a higher median than the number of runs scored in a League A park.

C.Yes because the number of runs scored in a League A park appear to have a higher median than the number of runs scored in a League B park.

D.No because the number of runs scored in a League A park is about the same as the number of runs scored in a League B park.

On January 1, Park Corporation and Strand Corporation had condensed balance sheets as follows:

On January 2, Park borrowed $60,000 and used the proceeds to obtain 80 percent of the outstanding common shares of Strand. The acquisition price was considered proportionate to Strand’s total fair value. The $60,000 debt is payable in 10 equal annual principal payments, plus interest, beginning December 31. The excess fair value of the investment over the underlying book value of the acquired net assets is allocated to inventory (60 percent) and to goodwill (40 percent).

On a consolidated balance sheet as of January 2, what should be the amount for current assets?

On a consolidated balance sheet as of January 2, what should be the amount for noncurrent assets?
