2.   Understanding what maturity risk means for bonds is very important. Complete the following table by calculating the new bond prices and then the % price change that results for the two bonds given. For example, in the table if interest rates go up 1% on the short term bond, that means that the YTM would go from 4% to 5%. Then calculate the new price at a YTM of 5% and then calculate the % change in price from today's price of $1,000 to the new price.

Short term bond: Face value of $1,000 with an annual coupon rate of 4% with semi-annual payments, and a maturity in 2 years. Assume that today's YTM on a 2 year bond is 4% so therefore today's price is $1,000.

Long term bond: Face value of $1,000 with an annual coupon rate of 5% with semi-annual payments, and a maturity in 30 years. Assume that today's YTM on a 30 year bond is 5% so therefore today's price is $1,000.

a. Obtain the linear trend equation for the following data on new checking accounts at Fair Savings Bank and use it to predict expected new checking accounts for periods 16 through 19. (Round your intermediate calculations and final answers to 2 decimal places.)

b.Use trend-adjusted smoothing with α = .2 and β = .1 to smooth the new account data in part a. What is the forecast for period 16? Compute the initial trend estimate (T_t) for Period 5 as follows: (Period 4 data – Period 1 data) / 3. Then compute the initial trend-adjusted forecast (TAF_t) for Period 5 as follows: Period 4 data + Initial trend estimate for Period 5. Then compute all remaining values (including the S_t value for Period 5) using the textbook formulas or Excel template. (Round the "Trend"values (Tt) to 3 decimal places and all other intermediate forecast values (TAFt and St) to 2 decimal places. Round your final answer to 2 decimal places.)

Experiment 4

Dr. Brown wanted to observe the effects of music genre on surgical recovery time. Dr. Brown set up an experiment in which participants were randomly assigned to listen to one of three different genres of music (rap, metal, or country). Participants were patients who had just received liposuction; they listened to their assigned music genre for 2 hours each day until discharged from the hospital. Dr. Brown recorded the number of days the patients remained in the hospital. His results are shown below.

Using the data shown below, conduct the appropriate statistical test in SPSS to determine whether there is a statistically significant difference between any of the pairs of musical genres.

Data Structure in Java

The following java method counts how many triples of integers in an array of n distinct integers sum to zero.

public static int count(int[] a) {
   int n = a.length;
   int count = 0;
   for (int i = 0; i < n; i++) {
      for (int j = i+1; j < n; j++) {
         for (int k = j+1; k < n; k++) {
            if (a[i] + a[j] + a[k] == 0)
               count++;
         }
      }
   }
   return count;
}

For example: the following list

[8, -12, 9, 2, 4, -9, -2, 5]

has two triples that sim to zero: (8, -12, 4) and (4, -9, 5).

The problem here is that this is a bad solution to solve the problem and it takes Big O(n^3).

Find another solution to the problem that takes less than O(n^3) of time complexity

Hint 1: Sort the array first (use Java’s built-in Arrays.sort(int[] a)) method to sort the array first.

Hint 2: A pair a[i] and a[j] is part of a triple that sums to zero if and only if the value -(a[i] + a[j]) is in the array (but not a[i] or a[j]).

2. A researcher for Netflix wants to know if people have different preferences for two shows: Friends and The Office.  The researcher recruits 7 people.  Each person watches five minutes of Friends and rates the show on a scale of 0-10, where 0 means they hate it and 10 means they love it.  Then each person watches five minutes of The Office rates the show on a scale of 0-10.  Assume that you are working at the .05 level of significance. The researcher obtains the following data:

1. State the appropriate null and alternative hypotheses (in symbols, referring to the population means).       

2. Identify the critical value(s).

3. Calculate  .

4. Calculate the t statistic.  (The appropriate standard error that you need in the denominator when you compute t is 0.87.)
