2.) Boston Railroad decided to use the high-low method and operating data from the past six months to estimate the fixed and variable components of transportation costs. The activity base used by Boston Railroad is a measure of railroad operating activity, termed “gross-ton miles,” which is the total number of tons multiplied by the miles moved.

Determine the variable cost per gross-ton mile and the fixed cost.

3.) For a recent year, Wicker Company-owned restaurants had the following sales and expenses (in millions):

Assume that the variable costs consist of food and packaging, payroll, and 40% of the general, selling, and administrative expenses.

a. What is Wicker Company's contribution margin? Round to the nearest million. (Give answer in millions of dollars.)
$ million

b. What is Wicker Company's contribution margin ratio? Round to one decimal place.
%

c. How much would income from operations increase if same-store sales increased by $1,900 million for the coming year, with no change in the contribution margin ratio or fixed costs? Round your answer to the closest million.
$ million

4.) Dragon Sports Inc. manufactures and sells two products, baseball bats and baseball gloves. The fixed costs are $369,000, and the sales mix is 30% bats and 70% gloves. The unit selling price and the unit variable cost for each product are as follows:

a. Compute the break-even sales (units) for both products combined.
units

b. How many units of each product, baseball bats and baseball gloves, would be sold at break-even point?

Several months ago, Ayers Industries Inc. experienced a hazardous materials spill at one of its plants. As a result, the Environmental Protection Agency (EPA) fined the company $258,000. The company is contesting the fine. In addition, an employee is seeking $202,000 in damages related to the spill. Lastly, a homeowner has sued the company for $310,000. The homeowner lives 35 miles from the plant but believes that the incident has reduced the home’s resale value by $310,000.

Ayers’ legal counsel believes that it is probable that the EPA fine will stand. In addition, counsel indicates that an out-of-court settlement of $140,000 has recently been reached with the employee. The final papers will be signed next week. Counsel believes that the homeowner’s case is much weaker and will be decided in favor of Ayers. Other litigation related to the spill is possible, but the damage amounts are uncertain.

Your task in this exercise is to write a function called get_playlist_tracks(database_filename, which_playlist), which formulates a SELECT statement that returns track name, album title, genre name, artist name and track composer for all tracks in the database which are associated with a given playlist. This statement requires several nested INNER JOINs to pull together data from the "tracks", "albums", "genres", "artists", and "playlists" table. The default ordering of tracks should be used. The result of the function is a list of database records. The parameter which_playlist specifies a playlist in the database. You first have to check if the playlist is contained in the "playlists" table, if not an error message as indicated in the examples has to be printed and an empty list has to be returned.

Don't forget to close the database connection after you have finished accessing it!

For example:

database_filename = 'chinook.db'
which_playlist = 'On-The-Go 1'
query_result = get_playlist(database_filename, which_playlist)

print(f"Playlist '{which_playlist}'")
for count, database_record in enumerate(query_result):
   print(f"{count:<2} Track Name: {database_record[0]}")
   print(f"   Album Title: {database_record[1]}")
   print(f"   Genre: {database_record[2]}")
   print(f"   Artist: {database_record[3]}")
   print(f"   Composer: {database_record[4]}")

Playlist 'On-The-Go 1'
0  Track Name: Now's The Time
   Album Title: The Essential Miles Davis [Disc 1]
   Genre: Jazz
   Artist: Miles Davis
   Composer: Miles Davis

database_filename = 'chinook.db'
which_playlist = 'Independent'
query_result = get_playlist(database_filename, which_playlist )

for database_record in query_result:
   print(database_record)

ERROR: Could not find playlist 'Independent' in database!

Using Java,

1. Ask for the runner’s name

2. Ask the runner to enter a floating point number for the number of miles ran, like 3.6 or 9.5

3. Then ask for the number of hours, minutes, and seconds it took to run

• A marathon is 26.219 miles

• Pace is how long it takes in minutes and seconds to run 1 mile.
  

Example Input:
What is your first name? // user enters Pheidippides
How far did you run today? 10.6 // user enters 10.6 miles

How long did it take? Hours: 1 // user enters 1 hours

Minutes: 34 // user enters 34 minutes

Seconds: 17 // user enters 17 seconds

Example Output:

Hi Pheidippides
Your pace is 8:53 (minutes: seconds)
At this rate your marathon time would be 3:53:12
Good luck with your training!

After your program tells the user what their pace is, your program will build a table showing the following columns. The pace table should start with the fastest man time which is Eliud Kipchoge.

Example:

Pace Table
Pace Marathon
4:37 2:01:04 ←- Eliud Kipchoge
5:17 2:18:41
5:57 2:36:18
6:37 2:53:55
7:18 3:11:32
7:58 3:29:09
8:38 3:46:46
8:53 3:53:12 ← Pheidippides

• The table should start with the World Record pace and time which is 4:37, 2:01:04.

• Then continues in 17 minute and 37 second intervals until you reach the marathon time of the user.

• Use a static function to print the pace table, introduce a while loop.

• For the first person it should call a printTable function

  • Example : printTable (pace, “<--- Eliud Kipchoge”) something like that

  • The pace table continues until it reaches the user

  • printTable (myPace, name) something like that  

• For the marathon and pace time, make sure the format has 0’s if the time is 9 seconds, it should be 09.

• Use the printf statement for formatting output (“02d %f%s”)

The price of Stock A today is 50, and stock B is 100. The probability of a booming, normal, and recessionary economy are 0.2, 0.7, and 0.1 respectively. If the economy is booming, stock’s A price will be 65 and stock B will be 108. If the economy is normal, stock’s A price will be 55 and stock’s B will be 105. If the econ falls into recession, stock’s A price will be 40 and stock’s B will be 102.
a) Calculate the expected return and standard deviation for each stock.
b) Assume you create a portfolio and put 50% of you money in stock A and 50% of you money in stock B. Calculate the portfolio expected return and standard deviation.

Please show formula and steps

1) A nutritionist claims that the proportion of females who consume too much saturated fat is lower than the proportion of males who consume too much saturated fat. In interviews with 513 randomly selected females, she determines that 300 consume too much saturated fat. In interviews with 564 randomly selected males, she determines that 391 consume too much saturated fat.

Do the data support the claim that the proportion of females who consume too much saturated fat is less than the proportion of males who consume too much saturated fat? Use α = 0.05 and the 4-step process.

2)

The developer of a new filter for filter-tipped cigarettes claims that it leaves less nicotine in the smoke than does the current filter. Because cigarette brands differ in a number of ways, he tests each filter on one cigarette of each of nine randomly selected brands and records the difference in nicotine content. His results are given in the table below.

Does the data give convincing evidence that the filter tips leave less nicotine in the smoke? Follow the 4-step process.

old=c(.7, .8, .8, .9, .9, 1, 1.2, 1.2, 1.8)

new=c(.6, .6, .7, .8, .7, 1, .8, .9, 1.5)

An investor with a stock portfolio worth several hundred thousand dollars sued his broker and brokerage firm because lack of diversification in his portfolio led to poor performance. The following data lists the rates of return, in percent, for a random sample of 39 months that the account was managed by the broker. The arbitration panel compared these returns with the average S&P 500 for the same period.

stock=c(-8.36, 1.63, -2.27, -2.93, -2.70, -2.93, -9.14, -2.64, 6.82, -2.35, -3.58, 6.13, 7.00, -15.25, -8.66, -1.03, -9.16, -1.25, -1.22, -10.27, -5.11, -0.80, -1.44, 1.28, -0.65, 4.34, 12.22, -7.21, -0.09, 7.34, 5.04, -7.24, -2.14, -1.01, -1.41, 12.03, -2.56, 4.33, 2.35)

Does the data show that the mean return is different from 0.95%, the average return for the S&P 500. Use α = 0.01 and the 4-step process.

4) A random sample of 328 medical doctors showed that 171 had a solo practice. Find and interpret a 95% confidence interval for the proportion of all doctors who have a solo practice. Follow the 4-step process.
