Final Answer:
1a. Table (ages and salaries):
- A: Age = 20, Salary = $1500
- B: Age = 23, Salary = $2200
- C: Age = 25, Salary = $2200
- D: Age = 25, Salary = $3200
- E: Age = 30, Salary = $2800
- F: Age = 38, Salary = $2600
- G: Age = 38, Salary = $3600
- H: Age = 43, Salary = $3000
- I: Age = 46, Salary = $4000
- J: Age = 50, Salary = $3800
1b. As age increases, salary generally increases, but not perfectly — there are exceptions (e.g., F is older than E but earns less; H is older than G but earns less).
1c. It may not be reasonable because the data only includes employees up to age 50, and the pattern may not continue past that — for example, salaries might plateau or even decrease after a certain age due to retirement, reduced hours, or other factors.
2a. Scatter plot points:
(5, 70), (10, 52), (15, 42), (20, 26), (25, 12), (30, 4) — plotted with temperature on x-axis, number of birds on y-axis.
2b. As temperature increases, the number of birds seen decreases — there is a strong negative relationship.
