Detergent Powder Formulations

Why Detergent PD3 is better than others two? is different amount CFAS, LABS, STPP, Sodium Sulfate and sodium Carbonate in this process affect the quality of the detergent? Explain why

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.

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.

Two boxplots, one above the other, share a horizontal axis labeled from 0 to 15 in increments of 1. The bottom boxplot is labeled A and has vertical line segments drawn at 4, 6, and 7. A box encloses the vertical line segments, and horizontal line segments extend from both sides of the box to 0 and 13. An x is plotted at 14. The top boxplot is labeled B and has vertical line segments at 3, 4.5, and 7. A box encloses the vertical line segments, and horizontal line segments extend from both sides of the box to 0 and 11.

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.

​b) Explain why a hypothesis test may be used to test whether the mean number of runs scored for the two types of ballparks differ.

Suppose that for all Miami University STA 261 students, the average distance that they live from campus is 12.2 miles with a standard deviation of 8.0 miles. A random sample of 49 Miami university STA 261 students was taken, and the sample average distance that they live from campus was calculated.

a. what is the shape of the population distribution? Briefly explain your response

b. What is the probability that a randomly selected MU STA 261 student lives at least 10 miles from campus?

c. What is the probability that the sample average will have a value of at least 10 miles?

74. A particular brand of tires claims that its deluxe tire averages at least 50,000 miles before it needs to be replaced. From past studies of this tire, the standard deviation is known to be 8,000. A survey of owners of that tire design is conducted. From the 28 tires surveyed, the mean lifespan was 46,500 miles with a standard deviation of 9,800 miles.

Using alpha = 0.05, is the data highly inconsistent with the claim?

In other words, is there convincing evidence (at the 5% significance level) that the deluxe tires actually average less than 50,000 miles before needing to be replaced?
