1. The annual precipitation measurements (Pi in cm) for M city, over a 20year period are shown in the following table. Determine the mean, standard deviation, and skew coefficient for this series.

2. Annual precipitation measurements (Pi in cm) for M City, were given in Problem 1. Determine the magnitude of the 10-year precipitation depth if the data fit:

1. the normal distribution.
2. the Gumbel distribution.

How many times was the P10 (normal) exceeded in the 20-year annual precipitation record given in Problem 1?

1. The annual precipitation measurements (Pi in cm) for M city, over a 20year period are shown in the following table. Determine the mean, standard deviation, and skew coefficient for this series.

2. Determine the mean, standard deviation, and skew coefficient for the log values of annual rainfall for M City, given in Problem 1. Also determine the mean precipitation (in cm) of the log-transformed data.

The federal government calculates its budget on a fiscal year that begins each year on October 1 and ends the following September 30. At the beginning of the 2003-2004 fiscal year, the Department of Finance forecast that the federal budget surplus for the fiscal year would be $4.0 billion. The actual budget surplus for the fiscal year was $9.1 billion. Federal expenditures were $1.7 billion less than the Department had forecast, and federal revenue was $1.5 billion more that the Department had forecast. The remainder of the surplus came from lower-than-forecast debt charges. a) Is it likely that the economy grew faster or more slowly during fiscal 2003-2004 than the Department of Finance had expected? Explain your reasoning. b) Suppose that the federal government was committed to balancing the budget each year. What actions of the government would have led to a balanced budget? And what will be the economic consequences? Explain. c) Does the surprise surplus during fiscal 2003-2004 provide any insight into difficulties that might arise in trying to balance the budget every year? Explain.

Meiosis Essay Question:

Three events in sexual reproduction contribute to genetic variation in a population: independent assortment, crossing over, and random fertilization.

Explain how the three processes of sexual reproduction are advantageous to organisms and generate genetic variation within a population.

- State which phase of meiosis is occurring during each of the three events.  

- Also, explain what is happing during these phases that results in the genetic diversity of offspring.

- How is this advantageous to the population of a species, and how does this contribute to evolution?

Mattel​ (U.S.) achieved significant sales growth in its major international regions between 2001 and 2004​. In its filings with the United States Security and Exchange Commission​ (SEC), it reported both the amount of regional sales and the percentage change in those sales resulting from exchange rate changes.

a. What was the percentage change in​ sales, in U.S.​ dollars, by​ region?

b. What were the percentage change in​ sales, by​ region, net of currency change​ impacts?

c. What impact did currency changes have on the level and growth of consolidated sales between 2001 and​ 2004?

1. Two researcher want to find out whether there is a difference among graduation rates (these are in percentages) of five colleges over a 10-year period. Using the Data set below, determine if there a difference between colleges? Do this manually and show all eight steps in computing. (HINT: There is one variable being examined (i.e. graduation rates) for more than two groups (i.e. college 1, 2, 3, 4, 5) that are tested only once).

2. How do you interpret = 18.9, p < .05?

3. If the correlation between variable X and variable Y is perfect, what do you know about the prediction?
