Answer:
-The question is not biased.
-The sample is biased because it does not represent the population of customers at the lawn and garden store.
Step-by-step explanation:
-The question is not biased.
The question posed by the survey to the participants was;
"Would you like the store to provide more annual flowers or more perennial flowers?"
The question takes into account both products, that is the annual flowers and the perennial flowers. Therefore, the question is not biased toward a response of wanting more annual flowers or toward a response of wanting more perennial flowers.
-The sample is biased because it does not represent the population of customers at the lawn and garden store.
On the other hand, the sample of participants captured by the survey is biased since the survey only targeted customers who bought perennial flowers. We would expect these participants to respond in favor of what they purchase; the perennial flowers. The survey should have targeted the population of customers at the lawn and garden store, that is both the annual and perennial flowers customers.
Let's write a system of generic linear equations:
ax + by = c
dx + ey = f
A system without solution:
It occurs when the system of equations has the coefficients of x and y proportional to each other, but not proportional to the free terms. That is to say:
(a) / (d) = (b) / (e) ≠ (c) / (f)
That is, the slopes are the same.
The cut point with y is different.
Answer:
The slopes are the same.
The cut point with y is different.
