Gun Murders - Texas vs New York - Significance Test
In 2011, New York had much stricter gun laws than Texas. For that year, the proportion of gun murders in Texas was greater than in New York. Here we test whether or not the proportion was significantly greater in Texas. The table below gives relevant information. Here, the p̂'s are population proportions but you should treat them as sample proportions. The standard error (SE) is given to save calculation time if you are not using software.

Data Summary

Standard Error (SE) = 0.02285

The Test: Test the claim that the proportion of gun murders was significantly greater in Texas than New York in 2011. Use a 0.01 significance level.

(a) Letting p̂₁ be the proportion of gun murders in Texas and p̂₂ be the proportion from New York, calculate the test statistic using software or the formulaz =

where δ_p is the hypothesized difference in proportions from the null hypothesis and the standard error (SE) is given with the data. Round your answer to 2 decimal places.
z =
To account for hand calculations -vs- software, your answer must be within 0.01 of the true answer.

(b) Use software or the z-table to get the P-value of the test statistic. Round to 4 decimal places.
P-value =

(c) What is the conclusion regarding the null hypothesis?

reject H₀

fail to reject H₀    

(d) Choose the appropriate concluding statement.

The data supports the claim that the proportion of gun murders was significantly greater in Texas than New York.

While the proportion of gun murders in Texas was greater than New York, the difference was not great enough to be considered significant.     

We have proven that the stricter gun laws in New York actually decreased the proportion of gun murders below the rate in Texas.

We have proven there was no difference in the proportion of gun murders between Texas and New York.

Write two Java programs and verify that they work.

Program 1 should:

• Read a UTF-8 encoded text file
• Print to the console the hex values for the bytes it read in.
• Convert the text to UTF-16
• Print to the console the hex values for the converted bytes
• Write the UTF-16 text to a file

Program 2 should do the same as program 1, except program 2 goes from UTF-16 to UTF-8

Note: we are supposed to write two java programs, the first program should read utf8 encoded text file and the second program should write utf16 text file. So, if you can give me the java code that can read and write utf8 and utf16 text files respectively , I would be happy. Thank you.

You have developed the overall Virtual Private Cloud (VPC) design for the cloud initiative for Get-Sole Shoes. Now it is time to examine the infrastructure that would be used within the VPC.

From this week’s reading, review the use of Elastic Compute Cloud (EC2) within a VPC for the servers that will be needed for the company.

Respond to the following in a minimum of 175 words:

• Discuss possible EC2 designs that can be used for the company. Discuss your rationale for your EC2 recommendations and remember to keep cost (four pillars of cost optimization) as part of your recommendations.

1)If an algorithm performs N steps then we say it is O(N) ?

2) An example of something that is O(N) is(chose one)

A)printing to the screen.B)executing a conditional statement. C) initializing an integer variable. D) looping through an array of size N.

3)Suppose we found the run time of an algorithm was O(2N³ + 4N² + 5N + 3). What is the Big O notation for the algorithm?

A) O(5N), B) O(4N^2), C) O(N^3), D) O(2N^3)

Think of one knowledge area and one skill that you would like to improve on. Report what those are.

1.) Develop a training program for either the knowledge area or the skill. You do not need to do both.

2.) Develop / set the criteria. What criteria will you examine?

3.) Choose a study design

4.) Choose a criteria measure.

5.) How will you measure that criteria? Explain how your measure assesses the criteria.

Multiplication of Matrix is one of the tasks that takes time to compute. Note that the time complexity of multiplying two square matrix is o(n^3) using the nested loops method, and Strassen algorithm improves it to O(n^2.8074). Multi-threading can be used to further enhance this.

Using the matrices below, write

(a) a serial program (the normal nested loops method) to perform the multiplication.

(b) a multithreaded program using pthreads to perform this computation.

(c) compare the execution times of (a) and (b) in a table.

1. Investigate the difference between "phase velocity" and "group velocity." Why does an index of refraction of less than 1 (so v>c) not violate relativity, which says no information can move faster than the speed of light?

While an inventory policy includes two decisions, use an example to explain what the two decisions are:
