You were again promoted by the mayor for getting her good information about lead levels in dogs. She has appointed you the new senior health officer of the city of Sarasota. Your first task is to check the results of a report that the previous health officer completed. The mayor thinks there might be some calculation errors in the data presented. You need to determine the mean, median, mode, range, standard deviation and variance of the following data. Produce a graph that allows the mayor to determine if the data are normally distributed.

1. Reflect on the concept of polynomial and rational functions.
2. What concepts (only the names) did you need to accommodate these concepts in your mind?
3. What are the simplest polynomial and rational function you can imagine?
4. In your day to day, is there any occurring fact that can be interpreted as polynomial and rational functions?
5. What strategy are you using to get the graph of polynomial and rational functions?

Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups.
Problem Set 2: Two-way mixed design ANOVA (8 pts) Research Scenario: A researcher is attempting to determine the effects of age and sleep deprivation on a reaction time task. Participants (5 “old”; 5 “young”) in an experiment are given a computerized search task. They search a computer screen of various characters and attempt to find a particular character on each trial. When they find the designated character, they press a button to stop a timer. Their reaction time (in ms) on each trial is recorded (note, so the lower the number, the faster the time). Participants each underwent all three sleep conditions across three days - after having 0, 4, or 8 hours of sleep (times were counterbalanced). The reaction time data for the 10 participants appear below. Using this table, enter the data into a new SPSS data file and run the appropriate test to assess whether sleep deprivation and/or age affect performance on reaction time. Remember that between subjects variables such as “Age” will be represented using a single column in SPSS. Within subjects variables such as sleep would be represented in multiple columns – one per level. Hint: for this data entry, you will end up for a total of four columns in SPSS.

For each problem (A and B),
- Seek power series solutions of the given differential equation about the given point x0 and find the recurrence relation.
- Find the first four terms in each of two solutions y1 and y2 (unless the series terminates sooner).
- By evaluating the Wronskian W(y1, y2)(x0), show that y1 and y2 form a fundamental set of solutions.
- If possible, find the general term in each solution.
A) (1 - x)y" + y = 0; x0 = 0
B) xy" + y' + xy = 0; x0 = 1

Consider the statement, “For all natural numbers n,n, if nn is prime, then nn is solitary.” You do not need to know what solitary means for this problem, just that it is a property that some numbers have and others do not.
Write the converse and the contrapositive of the statement, saying which is which. Note: the original statement claims that an implication is true for all n,n, and it is that implication that we are taking the converse and contrapositive of.
Write the negation of the original statement. What would you need to show to prove that the statement is false?
Even though you don't know whether 10 is solitary (in fact, nobody knows this), is the statement “if 10 is prime, then 10 is solitary” true or false? Explain.
It turns out that 8 is solitary. Does this tell you anything about the truth or falsity of the original statement, its converse or its contrapositive? Explain.
Assuming that the original statement is true, what can you say about the relationship between the set PP of prime numbers and the set SS of solitary numbers. Explain.

In the world of professional sports (football, baseball, basketball), teams which have an operating profit often have a worse win-loss record compared to teams with lower operating profits or an operating loss (teams with the best players win, and the best players cost money). (a) Would you consider a professional sports team to be a profit maximizer? Please explain.
(b) If your answer to (a) is no, then what financial reason is there for anyone to own a professional sports team? Please explain.

Suppose we use the ElGamal signature scheme with p = 65539, ? = 2, ? = 33384. We send signed messages (m, r, s): (809, 18357, 1042) = hi and (22505, 18357, 26272) = bye. (a). Show that the same value of k was used for each signature. (b). Use this fact to find this value of k and to find the value of “a” such that ? ≡ ?? (??? ?).
