Answer:
The anwer is the availability heuristic.
Explanation:
The availability heuristic is a thinking bias that occurs when a person reccurs to immediately aviable, usually recent information to back up his thoughts or beliefs.
In the example, Mariah is assuming that her two best friends' situation can be applied for a larger population, <u>simply because that's the available information for her</u>.

The post world war II record shows that recessionary gaps may be long-lasting because <u>deflation</u> tends not to occur.
Deflation is when customer and asset prices lower over time, and shopping power will increase. Essentially, you may buy greater goods or offerings the day after today with the identical amount of cash you've got nowadays. this is the replicate picture of inflation, that is the gradual growth in costs across the economy.
Deflation is when the charges of products and offerings decrease throughout the complete economic system, increasing the shopping power of clients. it is the opposite of inflation and may be taken into consideration as terrible for a state as it can signal a downturn in an economic system, leading to a recession or despair.
A recessionary gap, or contractionary gap, happens when a rustic's actual GDP is decreased than its GDP at complete employment. Recessionary gaps near when actual wages go back to equilibrium, and the number of exertions demanded equals the amount supplied

Answer:
1. Co-variance= -1.2
2. correlation coefficient= -0.4404
3. There is weak negative relationship between x and y.
Explanation:
1.
Co-variance= Cov(x,y)= sum[(x-xbar)(y-ybar)]/n
xbar=sumx/n=32/5=6.4
ybar=sumy/n=35/5=7
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
Cov(x,y)= sum[(x-xbar)(y-ybar)]/n=-6/5=-1.2
Cov(x,y)=-1.2
2.
correlation coefficient=r
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
(x-xbar)² 0.36 2.56 1.96 11.56 6.76
(y-ybar)² 0 4 4 0 0
r=-0.4404
3. Since the value of correlation coefficient is negative and less than 0.5 , so, we can say that there is weak negative relationship between x and y.
