If you estimate the beta OLS for stock i is 1.5, the standard error is 0.3. To test the two null hypothesis:β=3.5,β=-1，can you reject these two null hypotheses at 10% significance level with the t_critical = 2.96?

1. A.	β=3.5 cannot be rejected,β=-1 can be rejected
   	B.	β=3.5 can be rejected,β=-1 cannot be rejected
   	C.	β=3.5 can be rejected,β=-1 can be rejected
   	D.	β=3.5 cannot be rejected,β=-1 cannot be rejected

Imagine that a society has a gini coefficient of 0.3. According to the Maximin Criterion has this society reached the efficient level of redistribution? Explain your answer

Consider a stock priced at $30 with a standard deviation of 0.3. The risk-free rate is 0.05. There are put and call options available at exercise prices of 30 and a time to expiration of six months. The calls are priced at $2.89 and the puts cost $2.15. There are no dividends on the stock and the options are European.   

What is the profit from the transaction from a finance perspective (adjusting for the TVM)?

$7.00 ?

$4.11 ?

$4.04 ?

$3.96 ?

none of the above ?

Assume that the stock begins paying a dividend of 3% and the price of the call option falls to $2.75. What is the price of the put in this situation?

The probability is 0.3 that a traffic fatality involves an intoxicated or​ alcohol-impaired driver or nonoccupant. In eight traffic​ fatalities, find the probability that the​ number, Y, which involve an intoxicated or​ alcohol-impaired driver or nonoccupant is a. exactly​ three; at least​ three; at most three. b. between two and four​, inclusive. c. Find and interpret the mean of the random variable Y. d. Obtain the standard deviation of Y.

An activated sludge process with an aeration basin volume of 0.3 MG is treating wastewater with the average daily flow of 2 MGD. The raw sewage entering the treatment plant has an average BOD5 of 400 mg/L. The primary treatment removes 25% of BOD5 and the subsequent activated sludge process is designed to remove 90% of BOD5.

Given:

Plant effluent BOD5 concentration = 30 mg/L

Biomass concentration in the aeration tank = 2,000 mg/L

Biomass concentration in the plant effluent = 20 mg/L

Biomass concentration in the recycle (RAS) = 8,000 mg/L

Flow rate of waste sludge (WAS) = 0.025 MGD

Endogenous decay rate (kd) = 0.01 day-1

a) Calculate the MCRT of the process.

b) Determine the yield coefficient, Y.

c) If µnet, nitrifiers = 0.2/day, would you expect to get nitrification in this system? Briefly describe why or why not and show any supporting calculations.
