Instructions
Modify the Product class from the Practice Exercise 7 by adding a quantity member. Include a getter and setter, using decorators, and modify the appropriate constructor to also accept a quantity parameter.
Then modify the inventory.py file from the practice exercise to include quantity values in the constructor calls with a quantity of 100 for product1 (hammers) and 3000 for product2 (nails). Add print statements to display the quantity values as shown in the Expected Output included below.
Submission
Attach and submit your modified product.py and inventory.py files to this assignment.

5.30 Husbands and wives, Part II. Exercise 5.6 presents a scatterplot displaying the rela- tionship between husbands’ and wives’ ages in a random sample of 170 married couples in Britain, where both partners’ ages are below 65 years. Given below is summary output of the least squares fit for predicting wife’s age from husband’s age.
60
40
20
20 40 60
Husband's age (in years)
(Intercept) age husband
Estimate 1.5740 0.9112
Std. Error 1.1501 0.0259
t value 1.37 35.25
Pr(>|t|) 0.1730 0.0000df = 168
(a) We might wonder, is the age difference between husbands and wives consistent across ages? If this were the case, then the slope parameter would be β1 = 1. Use the information above to evaluate if there is strong evidence that the difference in husband and wife ages differs for different ages.
(b) Write the equation of the regression line for predicting wife’s age from husband’s age.
(c) Interpret the slope and intercept in context.
(d) Given that R2 = 0.88, what is the correlation of ages in this data set?
(e) You meet a married man from Britain who is 55 years old. What would you predict his wife’s
age to be? How reliable is this prediction?
(f) You meet another married man from Britain who is 85 years old. Would it be wise to use the same linear model to predict his wife’s age? Explain.

Last Sunday night at the local hospital was really busy, and the
folks in the maternity ward got just a little bit flustered. Two
pairs of twins were born that night within a few moments of each
other, but somehow the staff forgot to put name tags on the babies,
and now they don't know which babies belong to which parents. You
need to help them out by analyzing the blood types of these four
babies and the two couples who are anxiously waiting to take their
new families home with them.
Here's what you know:
You know about the inheritance patterns of human ABO blood types
You know the blood types of the two sets of parents:
Mrs. Smith is blood type A, and her husband is blood type B.
Mrs. Abernathy is blood type O and her husband is blood type AB.
And you know the blood types of the four babies (all little girls, incidentally):
Baby #1 is blood type O
Baby #2 is blood type A
Baby #3 is blood type B
Baby #4 is blood type AB
What could be simpler? On the answer sheet, tell me which two babies you're going to send home with Mr. and Mrs. Smith, and which you are going to send with Mr. and Mrs. Abernathy. (Please identify the babies by their numbers, shown above.) Then explainexactly how you figured it out. Show work as needed for your explanation, including Punnett squares for each of these couples.

Mr. Wiggins is a 78-year-old African American male with chronic kidney disease, which requires dialysis. The etiology of his renal disease was multifactorial—long-standing uncontrolled HTN and DM nephropathy. He has been on hemodialysis for the past 10 years and has done relatively well. Four weeks ago, he had a major CVA and is minimally responsive. His condition is not expected to change, and the family is having a difficult time with his recent health changes. Advanced directives were discussed with them, and his wife is a durable power of attorney for his health care. The wife hates to see her husband this way and understands this is not how he would want to go on, but their children and many of the family members (his brothers and sisters) think the patient will return to himself. They want everything done in terms of life support measures—full code status. His family wanted a feeding tube placed, and he is now receiving 24-hour tube feedings. You are the NP caring for Mr. Wiggins. You have known and cared for him and his wife for several years. The wife pulls you aside, shares her dilemma, and asks you to make the decision regarding continuing medical care/support for her husband. How will you respond?
Post an explanation of potential outcomes of the patient in the case study you selected. Then, explain how care, treatment, and/or support may be facilitated for the patient. Include how you might address the needs of the patient’s family as well.
