The shape of the distribution of the time required to get an oil change at a 15​-minute ​oil-change facility is unknown.​ However, records indicate that the mean time is 16.3 minutes​, and the standard deviation is 4.3 minutes. Complete parts ​(a) through ​(c).
​(a) To compute probabilities regarding the sample mean using the normal​ model, what size sample would be​ required?
A. The sample size needs to be greater than or equal to 30.
B. The normal model cannot be used if the shape of the distribution is unknown.
C. Any sample size could be used.
D. The sample size needs to be less than or equal to 30.
(b) What is the probability that a random sample of nequals 35 oil changes results in a sample mean time less than 15 ​minutes?
The probability is approximately:
​(Round to four decimal places as​ needed.)
(c) Suppose the manager agrees to pay each employee a​ $50 bonus if they meet a certain goal. On a typical​ Saturday, the​ oil-change facility will perform 35 oil changes between 10 A.M. and 12 P.M. Treating this as a random​ sample, there would be a​ 10% chance of the mean​ oil-change time being at or below what​ value? This will be the goal established by the manager.
There is a​ 10% chance of being at or below a mean​ oil-change time of
nothing minutes.

Round all $ problems to the nearest cent.

All other calculations must be to at least the fifth decimal place.

Given the following information: (all numbers are in millions)

Variable rate CD’s = $90 Treasury bills = $150

Discount Loans = $20 Treasury notes = $100

Fixed rate CDs =$160 Money Market deposit accts. = $140

Savings deposits =$90 Fed Funds borrowing = $40

Variable rate mortgage loans = $140 Demand Deposits = $40

Primary Reserves = $50 Fixed rate loans =$210

Fed Funds Lending = $50 Equity Capital = $120

A. Develop a balance sheet from the above data. Be sure to divide your balance sheet into rate-sensitive assets and liabilities as

   we did in class and in the examples.

B. Perform a Standard Gap Analysis and a Duration Analysis using the above data if you have a 1.15% decrease in interest rates

   and an average duration of assets of 5.4 years and an average duration of liabilities of 3.8 years.

C. Indicate if this bank will remain solvent after the valuation changes. If so, indicate the new level of equity capital after the

   valuation changes. If not, indicate the amount of the shortage in equity capital.

You will be paying $10,800 a year in tuition expenses at the end of the next two years. Bonds currently yield 9%.

a. What is the present value and duration of your obligation? (Do not round intermediate calculations. Round "Present value" to 2 decimal places and "Duration" to 4 decimal places.)

Present value $
Duration years

b. What is the duration of a zero-coupon bond that would immunize your obligation and its future redemption value? (Do not round intermediate calculations. Round "Duration" to 4 decimal places and "Future redemption value" to 2 decimal places.)

Duration years
Future redemption value $

You buy a zero-coupon bond with value and duration equal to your obligation.

Exercise 4:

Consider an Australian financial institution which has Swiss Franc denominated assets worth 50 million CHF and USD denominated liabilities worth 1 million USD. The past exchange rates in over the past 10 months are:

a) Measure the exposure: Calculate the value of the position in AUD.

b) Measure the sensitivity: Calculate the change (in AUD) in the CHF position for a 1% increase in the value of the Swiss Franc. Calculate the change (in AUD) in the USD position for a 1% increase in the value of the USD.

c) Calculate the past changes in the exchange rate in %.
d) Re-evaluate the portfolio position with the past changes in the exchange rate. e) Calculate the Value at Risk for the next month and α = 10%
f) Calculate the Value at Risk for the next month and α = 20%

A new drug called Xaelenfal is on the market. Xaelenfal is an AMPA receptor antagonist, meaning that it binds onto AMPA receptors without activating them and prevents glutamate from binding.

i. If I take the drug Xaelenfal, how will this effect EPSPs recorded in the postsynaptic neuron when an excitatory presynaptic neuron fires an action potential? (1 point)

ii. How will the drug Xaelenfal effect IPSPs in the postsynaptic neuron when an inhibitory presynaptic neuron fires an action potential? (1 point)

iii. In a normal brain, synapses can get stronger when a presynaptic cell repeatedly causes a postsynaptic cell to depolarize (we call this long-term potentiation, or LTP). Explain how long term potentiation works including the following details. (3 points)
- Name the neurotransmitter that is released by the presynaptic cell.
- Name the receptor that this neurotransmitter binds to on the postsynaptic cell to mediate normal excitatory transmission.
- What other receptors are involved and how do they get recruited?
- List one way in which the presynaptic neuron changes and one way in which the postsynaptic neuron changes during LTP.

iv. Given what you know about plasticity, could Xaelenfal effect the ability of synapses to potentiate. Explain your answer. (2 points)
