If the decision in the hypothesis test of the population correlation is to reject the null hypothesis, what can we conclude about the population correlation?
Answer(s): B
The Ho is always stated as Ho: Population parameter=0. So if we reject Ho, we say that it is not zero.
As the head of a trading desk at a major bank, it is your job to evaluate whether the superior performance of a trader is due to skill or luck. To test this, you set up the following hypothesis:Ho: Expected excess returns = 0H1: Expected excess returns > 0The excess returns are returns adjusted for risk using a proprietary factor model. In this set-up, which of the following is/are true?
Answer(s): D
The alternative hypothesis, H1, does not assign a specific value to the expected excess return but specifies a directional region. Since it specifies the region to the right of 0 as an alternative, he must employ a right-tailed test i.e. a one-sided test. Note that the critical z-statistics in one-tailed regressions are always lower than the z- statistics in the corresponding two-tailed test.
If you buy a computer for $950 and agree to pay for it with 24 payments of $35 with the first payment occurring next month, what is the size of the final payment needed at month 24 to completely pay off the computer?

This question describes a situation often called a balloon payment. On the BAII Plus, press 24 N, 16 divide 12 = I/Y, 950 PV, 35 +/- PMT, CPT FV. On the HP12C, press 24 n, 16 ENTER 12 divide i, 950 PV, 35 CHS PMT, FV. The answer is shown as a negative number. Make sure the BAII Plus has the value of P/Y set to 1.

A cola dispensing machine is set to dispense a mean of 2.02 liters into a container labeled 2 liters. Actual quantities dispensed vary and the amounts are normally distributed with a standard deviation of 0.015 liter. What is the probability a container will have less than 2 liters?
z = (x-u)/sigma = 2 - 2.02/0.015 = -1.33 (negative since it is below the mean). The area between - infinity and z = -1.33 is 0.0918.

question 8 - can cloudtrail be used for storing jobs? based on aws - aws cloudtrail is used for governance, compliance and investigating api usage across all of our aws accounts. every action that is taken by a user or script is an api call so this is logged to [aws] cloudtrail. something seems incorrect here.
