1.Your friend brings a large bag of candy to class. In the bag of candy, there are 13 red candies, 20 blue candies, 13 orange candies, 5 yellow candies, 40 green candies, and 61 purple candies.

b.Your friend is going to reach into the bag and remove one candy at a time. Before your friend starts removing candies, you want to calculate the probability of selecting candies, in a specific order?

(each time a candy is removed from the bag, the total number of candies decreases)

P (red, purple, & green) =

P (red, blue, purple, & green) =

P (purple, yellow, red, orange, & purple) =

P (yellow, yellow, purple, purple, red, & red) =

P (red, red, green, purple, yellow, red, orange, yellow, & red) =

2.Calculate the standard deviation of the following sample:

12, 14, 15, 23, 22, 26, 28, 19, 17, 18, 25, 28, 29, 19, 12, 19, 22, 19, 23, 24, 19, 25, 19

Standard deviation=

3.One day, you are playing around with the change in your pocket. You decide to flip one coin and then you decide to flip two coins. Remember, a coin can land on either heads or tails and each coin flip is independent. Calculate the following probabilities:

One Coin Flip Probabilities:

P (heads) =

P (tails) =

Two Coin Flips Probabilities:

P (of at least one heads) =

P (of at least one tails) =

P (heads and heads) =

P (heads and tails) =

P (tails and tails) =

P (tails and heads) =

1. Assume we have a small jar full of 140 perfectly shaped jelly beans. Fifty of the jelly beans are red, 45 of the jelly beans are green, and 35 of the jelly beans are purple and 20 are black. If you randomly select one jelly bean, then …

1. What is the probability the jelly bean is red?
2. What is the probability the jelly bean is black?
3. What is the probability the jelly bean is green?
4. What is the probability the jelly bean is purple?
5. What is the probability you do not select a red jelly bean?
6. What is the probability the jelly bean is red or green?
7. What is the probability you do not select a red or green jelly bean?
8. Assume you pick a red jelly bean. Rather than put the jelly bean back in the jar, you eat it! You then randomly select another jelly bean from the jar.

1. What’s the probability that the jelly bean you select this time is red?
2. What’s the probability that the jelly bean you select this time is green?

3. What’s the probability that this jelly bean is not green?

1. Explain, in detail, the differences between leading, lagging, coincident, and unclassified economic indicators.
2. Explain one way in which economic statistics can be abused.

2. What is the difference between private and social cost? Provide an example and explain in details.

3. Give an example and explain in detail the differences between social and private benefits.

Parametric vs. Nonparametric Methods

The purpose of this assignment is to differentiate between parametric and nonparametric statistical methods. In addition, this assignment will help you understand and implement parametric or nonparametric statistical methods.

Research the following statistical topics:

• Levels of measurement
• Parametric and nonparametric methods

On the basis of your research and understanding, respond to the following:

• Find and state the definition of levels of measurement that distinguishes the five types of data used in statistical analysis.
• In your own words, compare the five types of data and explain how they differ.
• Find and state a definition of parametric and nonparametric methods that distinguishes between the two.
• In your own words, explain the difference between parametric and nonparametric methods.
• Explain which types of data require parametric statistics to be used and which types of data require nonparametric statistics to be used and why.
• Compare the advantages and disadvantages of using parametric and nonparametric statistics.
• Describe how the level of measurement helps determine which of these methods to use on the data being analyzed.

Use the class definition below to answer the following questions. [Total 8 Marks]

public class TrafficLight {

String stopLight = "red";

String waitLight;

String goLight;

public void setStopLight(String colour) {

stopLight = colour; }

public String getGreenLight() {

return goLight; } }

1 :How many field attributes are there in the TrafficLight class?

2 :Name a field attribute for this class.

3 :What is the name of the method that is an accessor?

4 :What is the name of the method that is a mutator?

5 :What is the output type for the setStopLight method ?

6 :Write a Constructor for the TrafficLight class that sets stopLight value to “red”, waitLight to “yellow” and goLight to “green”?

What are futures contracts? Give an example of how a futures contract can be used as protection against commodity price changes. Why did the price of the May WTI futures contract fall to about -$40. Is there a surplus of oil? What does this have to do with the state of the economy? Explain.

Note: Each WTI contract is for 1000 barrels of oil, and each barrel contains 42 gallons.

Please write at least 10 sentences.
