Both the quick and current ratios for 2016 decreased in the past year. The current ratio remains above 1.0, but this is driven in large part by high inventory levels, implying Nordstrom may have difficulty converting assets to cash. In addition, its interest coverage ratio remains high, indicating it has it may have difficulty making interest payments on its debt. Both the quick and current ratios for 2016 decreased in the past year but are higher than 1.0, implying Nordstrom is relatively liquid. Nordstrom's interest coverage ratio remains high, indicating it has the ability to cover interest payments on its debt. Both the quick and current ratios for 2016 decreased in the past year. The current ratio remains above 1.0, but this is driven in large part by high inventory levels, implying Nordstrom may have difficulty converting assets to cash. However, its interest coverage ratio remains high, indicating it has the ability to cover interest payments on its debt. Both the quick and current ratios for 2016 decreased in the past year but are higher than 1.0, implying Nordstrom is relatively liquid. Nordstrom's interest coverage ratio is weak, indicating it may have difficulty making interest payments on its debt.

Case study:

Miranda Miles is a 35-year-old white female. She has a 10-year history of cigarette smoking and refuses to quit after several educational teachings from health care providers and family members. There is no history of alcohol consumption. She has been married for five years and lives with her husband and son. Miranda works at a factory and her husband is a truck driver. She was admitted on August 7th, 2020 at 1700 with complaints of joint and back pain, difficulty performing ADL’s especially in the mornings, difficulty falling asleep due to chest pain, and a fever. Upon admission, the patient’s vitals were taken and blood was drawn. Diagnostic and laboratory testing resulted in a medical diagnosis of rheumatoid arthritis exacerbation.

Lab/Diagnostic Testing

Upon admission, the patient's joints were inspected and palpated to find any swelling. Findings in this patient’s case, spongy swelling has been found in knees and ankles and deformities in both hands and feet. Also, a complete blood count (CBC) was taken and white blood cells were found to be mildly elevated in response to inflammation. A synovial fluid culture will be taken as well. The synovial fluid was cloudy with elevated white blood cells. A rheumatoid factor test was also taken and results were positive. An MRI on her knee was ordered and findings include erosion of bone and destruction of cartilage which results in the patient's problem with limited range of motion and pain in knee.

Some car tires can develop what is known as "heel and toe" wear if not rotated after a certain mileage. To assess this issue, a consumer group investigated the tire wear on two brands of tire, A and B, say. Fifteen cars were fitted with new brand A tires and thirteen with brand B tires, the cars assigned to brand at random. (Two cars initially assigned to brand B suffered serious tire faults other than heel and toe wear, and were excluded from the study.) The cars were driven in regular driving conditions, and the mileage at which heal and toe wear could be observed was recorded on each car. For the cars with brand A tires, the mean mileage observed was 24.9924.99 (in 103103 miles ) and the variance was 7.757.75 (in 106106 miles22). For the cars with brand B, the corresponding statistics were 32.9232.92 (in 103103 miles) and 6.476.47 (in 106106 miles22 ) respectively. The mileage before heal and toe wear is detectable is assumed to be Normally distributed for both brands.

Part a) Calculate the pooled variance s2s2 to 3 decimal places. During intermediate steps to arrive at the answer, make sure you keep as many decimal places as possible so that you can achieve the precision required in this question.  ×106×106 miles 22

Part b) Determine a 95% confidence interval for μA−μBμA−μB, the difference in the mean 103103 mileages before heal and toe wear for the two brands of tire. Leave your answer to 2 decimal places. (  ,)

Part c) Based on the 95% confidence interval constructed in the previous part, which of the following conclusions can be drawn when we test H0:μA=μBH0:μA=μB vs. Ha:μA≠μBHa:μA≠μB with α=0.05α=0.05.

A. Reject H0H0 since 0 is in the interval found in part (b).
B. Reject H0H0 since 0 is not within the interval found in part (b).
C. Do not reject H0H0 since −7.93−7.93 is within the interval found in part (b).
D. Do not reject H0H0 since 0 is not in the interval found in part (b).
E. Do not reject H0H0 since 0 is within the interval found in part (b).

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.

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!
