A box encloses the vertical line segments at 8, 21, and 35, and horizontal line segments extend outward from both sides of the box to the vertical line segments at 2 and 38. All values are approximate.
Interpret the boxplot. Choose the correct answer below.
A.Most stays were approximately
2121
days. The longest stay was
37.537.5
and the shortest stay was
1.51.5.
B.The potential outlier is relatively close to the other data points. Most stays fall with the first quarter of the boxplot, between
7.57.5
and
2121.
C.The potential outlying observation falls far from the rest of the data. The other stays vary from
11
to
2525
days. The majority of the stays were between
55
and
2323
days.
D.The two potential outlying observations fall far from the rest of the data. The other observations vary from
6.056.05
to
31.2531.25
days. The majority of the stays were between
10.2510.25
and
29.1529.15
days.

89. According to the acceleration principle: (a) a relatively small increase in consumer spending results in a relatively larger increase in inflation; (b) a relatively small increase in consumer spending perceived to be permanent results in a relatively larger increase in investment; (c) a relatively small decrease in the federal budget deficit results in an even LARGER increase in capital spending (due to momentum); (d) the faster interest rates decline, the faster investment spending declines.
90. In the early stages of an economic boom, a borrower’s risk is likely to be: (a) related to deflation; (b) due to sub-par food in the cafeteria; (c) due mainly to the solvency of the lender; (d) relatively low.

First, let's compute your monthly (don't forget to modify your interest rate, for monthly compounding!!) debt of the student loan. Your payments will start on September 2022 and nish on September 2032. Please compute your monthly payment (using the assumptions or your real data [amount loaned, interest rate and duration]) and the total interest you will pay.
2. Compute the monthly payment of your house and the total interest you will pay on it. You have until 2025 to get the money for the down payment and you will start paying your mortgage on September 2025 and continue until September 2055. Compute the total interest you will pay.

5. According to the textbook, which of the following statements
is (are) correct?
(x) The multiplier effect is the multiplied impact on aggregate
demand of a given increase in government purchases of goods and
services.
(y) The marginal propensity to consume (MPC) is defined as the
fraction of extra income that a household consumes rather than
saves and the larger the MPC the larger the multiplier
effect.
(z) According to the multiplier effect, an increase in government
purchases causes interest rates to increase which increases
investment spending.

C. (x) and (z) only D. (y) and (z) only.
E. (y) only
6. Which of the following statements is (are) correct?
(x) According to the textbook, an increase in government spending
on goods to build or repair transportation infrastructure and
education facilities shifts the aggregate demand curve to the right
and, in the long run, shifts the aggregate supply curve to the
right.
(y) According to the crowding-out effect, an increase in government
purchases causes interest rates to rise and the interest rate
increase causes an increase in investment spending.
(z) The multiplier effect amplifies the effects of an increase in
government expenditures, while the crowding-out effect diminishes
the effects.

Suppose overall health care spending rose from $7000 per person in 2006 to $7700 per person in 2007. [1] Calculate both the absolute change and percentage change in health care spending per person from 2006 to 2007. [2] Using 2006 as your starting year (2006 = year 0), determine an exponential equation that calculates the amount of health care spending over time assuming the annual percentage change stays the same. Clearly identify the variable names and symbols in your equation. [3] Using 2006 as your starting year (2006 = year 0), determine a linear equation that calculates the amount of health care spending over time assuming the annual absolute change stays the same. Clearly identify the variable names and symbols in your equation. [4] Create an Excel spreadsheet to compare the two growth models’ predictions for health care spending through the year 2021. Include a chart showing both models. Please clearly indicate the question number on your excel file and attach it to the test. [5] Which model first predicts that U.S. health care spending will reach a level of $10,000 per person? In what year will that occur?
