  1. Plot the cross-sectional average of deposits/assets and Non-Deposit Debt/assets across time.

You can calculate Non-Deposit Debt = Assets – Deposits – Equity. How have the averages
evolved? How would you interpret your results?

  1. Run OLS regressions of quarterly loan growth on non-deposit debt/assets (one quarter lagged value) controlling for bank size (i.e. one quarter lagged natural logarithm of total asset) and
    profitability (i.e. one quarter lagged return on assets) for the sub-sample of your data during the
    financial crisis (i.e. 2008Q1 – 2010Q1). You should have Bank and Time fixed effects in your
    regression. What is the sign and magnitude of the co-efficient on non-deposit debt/assets? Is the
    coefficient significant? How will you interpret the co-efficient? Justify your findings.
  2. Compute two measures / (ex-post) proxies for bank risk
    a. Risk weighted asset divided by total assets
    b. Non-performing loans divided by total loans
  3. Plot the cross-sectional average of the above two measures across time. How have the averages
    evolved across years? How would you interpret your results?
  4. Run OLS regressions of the two ex-post measures of bank risk on equity over assets (one
    quarter lagged values). Control for bank size (i.e. one quarter lagged natural logarithm of total
    asset) and profitability (i.e. one quarter lagged return on assets) on the entire sample. You
    should have Bank and Time fixed effects in your regression. What is the sign and magnitude of
    the co-efficient on equity/assets? Is the coefficient significant? How will you interpret the coefficient? Justify your findings.
    Note: Make sure you winsorize all your variables (per quarter at the 1st and 99th percentile) to
    remove outliers.

Qn7. A coin is tossed 3 times. What is the probability that the number of tails obtained will be 1? Express your answer as a fraction or a decimal number rounded to four decimal places.
Qn8. f a coin is tossed 5 times, and then a standard six-sided die is rolled 4 times, and finally a group of two cards are drawn from a standard deck of 52 cards without replacement, how many different outcomes are possible?

If a coin is tossed 5 times, and then a standard six-sided die is rolled 4 times, and finally a group of two cards are drawn from a standard deck of 52

cards without replacement, how many different outcomes are possible?

You can also solve this using technology.
Use The Fundamental Principle of Counting with the Combination Rule.
The experiments or tasks in this problem can be grouped into three basic types of activities, namely, tossing a coin 5
times, rolling a standard six-sided die 4
times, and drawing two cards from a deck of cards without replacement. To obtain the solution to the problem, the number of possible outcomes for each task is computed and then the Fundamental Principle of Counting is applied to the three tasks.
There are 25
outcomes possible when tossing a coin 5 times, 64 outcomes possible when rolling a standard six-sided die 4 times, and C252
outcomes possible when drawing two cards from a deck of cards without replacement. Applying the Fundamental Principle of Counting to these three tasks, we see that the total number of different outcomes possible is
25⋅64⋅C252=32⋅1296⋅1326=54991872
.Qn9.

Qn11. In a history class there are 8 history majors and 8 non-history majors. 4 students are randomly selected to present a topic. What is the probability that at least 2 of the 4 students selected are non-history majors? Express your answer as a fraction or a decimal number rounded to four decimal places.
Qn12.
Jill is ordering pizza at a restaurant, and the server tells her that she can have up to three toppings: black olives, chicken, and spinach. Since she cannot decide how many of the toppings she wants, she tells the server to surprise her. If the server randomly chooses which toppings to add, what is the probability that Jill gets just spinach? Express your answer as a fraction or a decimal number rounded to four decimal places.
