RTY Company’s year-end balance sheet for 2018 and forecasted quarterly cash flows for 2019 are given below. Company always pays for its purchases one quarter after the purchase. 50% of all sales are collected in the current quarter and 50% in the next quarter. Other expenses are paid in the current quarter. a. Prepare the quarterly cash budget for the company for 2019. b. Assuming all forecasts will be accurate, how much external long-term financing will the company need if the company does not want to use any short-term financing at all?

(1) Read in the data and create an R data frame named tennis.dfr 
that has the following names for its columns:  first.name, last.name,
major.match.wins, major.match.losses, overall.match.wins, 
overall.match.losses, major.titles, overall.titles.  (Note that the 
data file has several explanatory lines before the real data begin 
that should be skipped when reading in the data lines.)
NOTE:  For the file name, you must use the following web address (URL): 
"http://people.stat.sc.edu/hitchcock/tennisplayers2018.txt".  
Please do not have your code read in the file from your own personal directory.

(2) Create and add two more columns called major.winning.pct and 
overall.winning.pct (showing winning percentage in the "major" and 
"overall" categories, respectively) to this data frame.
  
Note that "winning percentage" is defined 
as (match wins)/(match wins + match losses).

(3) Sort the data frame by major titles, from most to least.  
Have your program print the sorted data frame.

(4) Perform a nested sort, sorting the data frame first by major
titles (from most to least), and then by major winning percentage 
(from most to least) within major-title levels.
Have your program print this sorted data frame.

(5) Have R extract the subset of the data frame consisting of players
with at least 6 major titles.  Call this new data frame: greatest.dfr
Have your program print this new data frame.

(6)  In the most efficient way possible, have R calculate the sample means 
for each of the numeric variables in the tennis.dfr data set.
(Hint: Extract the appropriate subset of the data frame first.)

(7) Use the write.table() function to write the data set tennis.dfr to an
external file simply called "tennisdata.txt".  Make sure the external file includes the column names.
Also, make sure the players' names are NOT surrounded by quotes in the 
external file.

A sample of 40 observations is selected from a normal population. The sample mean is 31, and the population standard deviation is 3. Conduct the following test of hypothesis using the 0.05 significance level.

H₀: μ ≤ 30

H₁: μ > 30

1. Is this a one- or two-tailed test?

• "One-tailed"—the alternate hypothesis is greater than direction.

• "Two-tailed"—the alternate hypothesis is different from direction.

2. What is the decision rule? (Round your answer to 3 decimal places.)

3. What is the value of the test statistic? (Round your answer to 2 decimal places.)

4. What is your decision regarding H₀?

• Do not reject

• Reject

1. e-1. What is the p-value? (Round your answer to 4 decimal places.)

1. e-2. Interpret the p-value? (Round your answer to 2 decimal places.)

Mr. Chung has smoked two packs of cifarettes per day for 50 years. ABGs reveal a liw PO2 and a high PCO2 consitent with chronic lung disease. He is diagnosed with an acute exacerbation of chronic bronchitis. He is placed on oral antibiotics and long acting bronchodilators by metered dose inhaler. What teaching could you offer to help Mr. Chung mobilize and expectorate secretions?

Two lab groups dissolved 6g of cupric sulfate pentahydrate in approximately 50 mL of warm water. After it dissolved, they added 1.12g of iron fillings. Student A predicted the reaction would produce 1.28g of copper, while student B predicted there would be 1.54g of copper. Which student, A or B, do you agree with? Explain your reasoning with a short essay.

1. A 50-year-old woman has been experiencing a chronic cough for the past two months. She is a two pack per day smoker and has been for the past 30 years. She sees her PCP for the cough and is given an order for a chest x-ray at the local hospital. The x-ray report states, “nodule in lower lobe of right lung, worrisome for malignancy.” The PCP refers her for a biopsy of the nodule at the ambulatory surgery clinic, which substantiates the diagnosis of cancer in the pathology report. Two weeks later the same physician who did the biopsy performs a right lower lobectomy. Prior to discharge after surgery, the patient develops an infection, and the infectious disease specialist is asked to evaluate her and recommend the appropriate treatment course. Upon discharge, she receives care in her home for the next two weeks. Four weeks after surgery, radiation therapy is initiated, but her condition continues to deteriorate over the next few months with metastasis to the brain noted, at which point she decides to receive only palliative care.
   1. Classify the providers for each stage of the patient’s care noted above and outline their responsibilities.
   2. Explain the documentation that each provider will be creating as part of the patient’s record.
