Answer:
Consider the complete question is,
'Ms. Lane borrowed $1,000 from her bank for one year at an interest rate of 10 percent. During that year, the price level went up by 15 percent. Which of the following statements is correct?
a. Ms. Lane will repay the bank fewer dollars than she initially borrowed.
b. Ms. Lane's repayment will give the bank less purchasing power than it originally loaned her.
c. Ms. Lane's repayment will give the bank greater purchasing power than it originally loaned her.
d. Ms. Lane's repayment will give the bank the same purchasing power that it originally loaned her.'
Solution :
We have,
The borrowed amount, P = $ 1,000,
Interest rate, r = 10% = 0.1,
Time, t = 1 year,
Thus, the returned amount,
∵ A > P
⇒ Ms. Lane will repay the bank greater dollars than she initially borrowed.
Now, the price level went up by 15 percent,
∵ 1000 + 15% of 1000 = 1000 + 150 = 1500
And, 1500 > 1100
⇒ Ms. Lane's repayment will give the bank less purchasing power than it originally loaned her.
3) This is definitely a positive association, but the question is - is it linear?
Since a somewhat straight line can be drawn through the points, it is linear.
<span>Answer: positive linear association

4) Find the slope using the formula
m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out
Oh no! It seems that their is not a pattern in the association, so its nonlinear!
Answer: Negative nonlinear association
5) <span>
m = 80 - 66/ 5 - 3
m = 14/2
m = 7
Positive! But is it linear??
Let us draw a graph this time.
I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!
