Answer:
a) Proportion = 41.3%
b) Proportion = 9.18%
c) Proportion = 13.35%
d) Interest payment = $37.28
Explanation:
We have normal distribution with mean = 29 and standard deviation = 9
a) The proportion of the bank’s Visa cardholders pay more than $31 in interest is:
P(X > 31) = = P (Z > 0.22) = 1 - P (Z ≤ 0.22) =
1 - 0.58706 = 0.41294 = 41.3%
The proportion of the bank's Visa cardholders pay more than 31 dollars in interest is 41.3%.
b) The proportion of the bank’s Visa cardholders pay more than $31 in interest is:
P(X > 41) = = P (Z > 1.33) = 1 - P (Z ≤ 1.33) =
1 - 0.90824 = 0.09176 = 9.176% ≈ 9.18%
The proportion of the bank's Visa cardholders pay more than 31 dollars in interest is 9.18%.
c) The proportion of the bank’s Visa cardholders pay more than $31 in interest is:
P(X > 19) = = P (Z < -1.11) = 1 - P(Z ≤ -1.11)) =0.13350 = 13.35%
The proportion of the bank's Visa cardholders that paid less than 19 dollars in interest is 13.35%.
d) Let's suppose this amount of payment is Y:
Therefore P(X > Y) = 0.18
so P(X < Y) = 0.82
Utilizing standard normal approximation
P(X ≤ Y) = = P (Z ≤
) = 0.82
Form the standard normal table we find that = 0.92
Therefore,
Y - 29 = 9×0.92
Y - 29 = 8.28
Y = 8.28 + 29 = 37.28
Therefore $37.28 of interest payment is exceeded by only 18% of the bank's Visa cardholders.
Answer:
1. Point on x-axis will increase and so will the point on the y-axis
2. All of the above
Explanation:
1. The Production Possibilities Frontier shows the amount of resources needed to produce different quantities of two goods. It therefore allows one to see the trade-off in resources for producing more of one good vs the other.
When a factor of production leads to more efficiency in the production of a good, the frontier will increase. In this scenario, there has been a growth in technology which means that more of both goods can be produced. This will increase the PPF on both axis. (Refer to attached file).
2. All of the listed options have led to increases in the standard of living in the last century. More education means people can get better jobs and build more infrastructure. International trade has increased market access and increased wealth. Farm productivity is better so more people can be fed and improvement in technology is the main driver for growth.
Answer:
39: $182.46
Explanation:
In this problem, the daily production level at the lowest average cost per player and the average cost (in $) can be estimated by considering the graph (average cost (y) against production level (x)) in the previous question. By drawing the graph up to scale, it can be deduced from the graph that the lowest average cost is approximately $182.46 and the production level at that point is 39.
